Synthesis and reactivity of (1S)-N-(1-phenylethyl)maleimide towards nucleophiles: an application to preparation of chiral pyrroloisothiochroman and pyrrolobenzo[d]thiepine based on pi-cationic cyclization

Chiral pyrroloisothiochroman and pyrrolo[d]thiepine were obtained efficiently in four steps from N-alkylated maleimides via, successively, sulfurization, regioselective reduction followed by pi -cationic cyclination of the N-acyliminium ion intermediates. These latter, in addition, led to conjugate enamides as a consequence of the dehydration reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.

Gold(I)-Catalyzed Cyclization/Nucleophilic Substitution of 1-(N-Sulfonylazetidin-2-yl) Ynones into N-Sulfonylpyrrolin-4-ones

Polysubstituted pyrrolin-4-ones have been efficiently synthesized from readily available 1-(N-sulfonylazetidin-2-yl) ynones via gold(I)-catalyzed cyclization/nucleophilic substitution in the presence of various nucleophiles, such as water, alcohols, or indoles. Additionally, 3-iodopyrrolin-4-one derivatives have also been obtained under the same reaction conditions upon addition of 1.2 equiv of N-iodosuccinimide.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 291756-76-8. HPLC of Formula: C7H14ClF6N2P.

Synthesis and evaluation of the anti-proliferative activity of diaryl-3-pyrrolin-2-ones and fused analogs

Analogs containing a central 3-pyrrolin-2-one core with different methoxyphenyl and/or indole substituents were prepared and tested for anti-proliferative activity in U-937 cells. The most efficacious analogs were non-rigid, (non-fused) contained methoxyaryl groups located at the 4-position, and contained either methoxyaryl or indole groups located at the 3-position. Both the number of methoxy groups contained in the substituents and the particular location of the indole rings with respect to the lactam carbonyl had significant affects on anti-proliferative activity. This work provides a framework to better understand structure-activity relationships for inducing anti-proliferative activity in diaryl heterocyclic scaffolds. (C) 2016 Elsevier Ltd.

Water mediated procedure for preparation of stereoselective oximes as inhibitors of MRCK kinase

Stereoselective aldoximes, preferably Z form have been obtained from ci-cyano substituted carbonyl conjugated alkenes. This reaction occurs through Michael addition type reaction followed by retro-Knoevenagel reaction without transition-metal catalysis via C-C bond cleavage. These oximes are evaluated against cancer cell lines employing mechanistic study. Two oximes showed significant cytotoxic activity, which through in silico studies were found to inhibit MRCK Kinase, responsible for metastatic spread of cancer mortality.

A Unique Mdm2-Binding Mode of the 3-Pyrrolin-2-one- and 2-Furanone-Based Antagonists of the p53-Mdm2 Interaction

The p53 pathway is inactivated in almost all types of cancer by mutations in the p53 encoding gene or overexpression of the p53 negative regulators, Mdm2 and/or Mdmx. Restoration of the p53 function by inhibition of the p53-Mdm2/Mdmx interaction opens up a prospect for a nongenotoxic anticancer therapy. Here, we present the syntheses, activities, and crystal structures of two novel classes of Mdm2-p53 inhibitors that are based on the 3-pyrrolin-2-one and 2-furanone scaffolds. The structures of the complexes formed by these inhibitors and Mdm2 reveal the dimeric protein molecular organization that has not been observed in the small-molecule/Mdm2 complexes described until now. In particular, the 6-chloroindole group does not occupy the usual Trp-23 pocket of Mdm2 but instead is engaged in dimerization. This entirely unique binding mode of the compounds opens new possibilities for optimization of the Mdm2 p53 interaction inhibitors.

Synthesis of Substituted Pyrrolin-4-ones from Amino Acids in Mild Conditions via a Gold-Catalyzed Approach

The gold-catalyzed cyclization of various alpha-amino-ynone derivatives gave the corresponding pyrrolin-4-ones in high yields. Moreover, the use of gold(III) oxide as catalyst allows a moderate to total stereocontrol during the cyclization. These pyrrolin-4-ones are highly useful intermediates for the synthesis of functionalized pyrrolidines and other natural products.

A new Ni(dmit)(2)-based organic magnetic charge-transfer salt, (m-PO-CONH-N-methylpyridinium) [Ni(dmit)(2)]center dot CH3CN

A new Ni(dmit)(2)-based organic magnetic charge-transfer (CT) salt, (m-PO-CONH-N-methylpyridinium)[Ni(dmit)(2)]center dot CH3CN, where PO = 2,2,5,5-Tetramethyl-3-pyrrolin-1-oxyl free radical and dmit = 2-Thioxo-1,3-dithiole- 4,5-dithiolate, was obtained, the crystal structure and magnetic properties of which are reported. Magnetic susceptibility of the CT salt obeys a combination of 1D ferromagnetic (1DF) Heisenberg (J(1DF) = +0.26 K) and Singlet-Triplet (ST) models (J(ST) = -51.2 K) with mean field (MF) approximation (J(MF) = -6.7 K), suggesting that spins on the PO radicals form 1D ferromagnetic chains and spins on the Ni (dmit)(2) monoanions form spin dimers at low temperature, the latter of which was also confirmed by band calculations.

2-(3-pyrrolin-1-yl)-1,4-naphthoquinones: Photoactivated alkylating agents

The preparation of 2-(3-pyrrolin-1-yl)-1,4-naphthoquinones and a study of their use as photoactivated alkylating agents is reported. The title compounds were easily synthesized by conjugate addition of the corresponding 3-pyrrolines to various naphthoquinones. Upon exposure to ambient room light, the compounds undergo an internal redox reaction to form 2-(pyrrol-1-yl)-1,4-hydroquinones, which are activated for nucleophilic addition by an S(N)1 azafulvene mechanism. Control experiments demonstrated that the redox reaction is triggered by light and that the nucleophilic addition does not proceed before this activation occurs. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008).
