Base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one

The base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one yields Morita-Baylis-Hillman (MBH) adducts instead of the expected aldol products in good to high yields (up to 97%). Various organic and inorganic bases are efficient catalysts for this reaction. Our study excluded the Morita-Baylis-Hillman mechanism for the formation of the MBH-type products. The MBH products are most likely formed as a result of the subsequent isomerization of the original aldol products between isatins and N-Boc-3-pyrrolin-2-one. (C) 2013 Elsevier Ltd.

Intermolecularly hydrogen-bonded dimeric helices: tripyrrindiones

A rare and unusual class of tripyrrolic compounds, violet-colored tripyrrin-1,14-diones, can be prepared easily and in moderately high yields from base (piperidine)-catalyzed condensation of 3-pyrrolin-2-ones with 2,5-diformylpyrroles. Dipyrrinones adopt the all-syn-Z conformation leading to helical, lock-washer like structures, which form dimers that are held together by intermolecular hydrogen bonds in nonpolar solvents and in the crystal. Strong bathochromic spectral shifts of the tripyrrindione similar to 480 nm long wavelength UV-visible absorption band are seen with added base: DBU, 615 nm; TFA, 573 nm; and Zn(OAc)(2), 586 nm.

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystin

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystim has been achieved using an alkylidene carbene 1,5-CH insertion reaction as a key step. The key cyclisation precursor was synthesised in high diastereomeric excess using a combination of known procedures, with the two key asymmetric centres being introduced via a Sharpless asymmetric epoxidation reaction. KHMDS induced 1,5-CH insertion produced a 3-pyrroline product, which was oxidised to the corresponding 3-pyrrolin-2-one using (1) TPAP/NMO; (2) NaCIO2; (3) NaBH4. The formal synthesis was then completed with a few standard functional group interconversions. (C) 2002 Published by Elsevier Science Ltd.

Simultaneous synthesis of thioesters and iron-sulfur clusters in water: two universal components of energy metabolism

Thioesters are important intermediates in both synthetic organic and biosynthetic reaction pathways. Here we show that thioesters can be synthesized in an aqueous reaction between thioacetate and thiols. The reaction can be coupled to a second reaction between sulfide and either ferrous or ferric iron, which drives the reaction forward. We furthermore demonstrate that sulfide released during thioester formation can be used in the synthesis of peptide bound [Fe-S] clusters, which like thioesters, are ancient components of metabolism. Together our results reveal a primordial linkage between high-energy ester formation and redox chemistry.

Acceptorless dehydrogenative coupling with Ru-based catalysts for the synthesis of N-heteroaromatic compounds

Ru-Catalyzed acceptorless dehydrogenative coupling (ADC) and auto-transfer-hydrogenative (ATH) reactions are effective, versatile transformations for the constructions of N-heteroaromatic compounds from alcohols. Water and hydrogen are the by-products and the starting alcohols are less toxic, more readily available and more easily handled than their halogenated counterparts. A variety of homogeneous ruthenium catalysts, alcohols and partner-substrates such as amines, ammonia, amidines and nitriles, have been used to build N-heteroaromatic compounds in one-pot, multi-step syntheses. This review details recently reported Ru catalysts employed for these reactions, describing the scope of each methodology, proposed reaction mechanisms, regioselectivity of coupling and applications in synthesis.
