Photosensitized oxidations of substituted pyrroles: Unanticipated radical-derived oxygenated products

(Chemical Equation Presented) Photooxidation of pyrrole adducts 7-10 has been investigated in order to establish a general reaction pattern andmechanism for the formation of the resulting oxygenated products. The reactions were performed in several solvents utilizing both type I and type II sensitizers. In most cases, photooxidations gave complex mixture of products. Among these products, 5,5- or 6,5-bicyclic lactams (11, 15, and 19), maleimide 12 unsaturated gamma-lactams (16 and 20), 5-hydroxylactams (13, 17, and21), and 5-methoxylactams (14, 18, and22) wereisolated and characterized. Photooxidation of 2,5-dimethyl-substituted pyrrole 10 in aprotic solvents unexpectedly afforded aldehyde 23 as the major product. Moreover, photooxidation of pyrrole adduct 10 in protic solvents exclusively gave the unprecedented solvent-trapped products 24-27. The formation of products 11-22 was rationalized by the intermediacy of a commonendoperoxide intermediate, whichcould be formedby both type I and type II mechanisms. Compounds 23-27 were most probably formed via an electron-transfer mechanism. 2009 American Chemical Society.

Catalytic, metal-free sulfonylcyanation of alkenes: Via visible light organophotoredox catalysis

The group transfer radical addition of olefins with tosyl cyanide has been accomplished via visible light-induced organophotoredox catalysis. A diverse array of olefins is amenable to this protocol, furnishing beta-sulfonyl nitriles with excellent efficiency under metal-free and redox-neutral conditions. A closed catalytic cycle is operative in this transformation, providing complementary reactivity to the classic radical chain process.

Enantioselective total synthesis and confirmation of the absolute and relative stereochemistry of streptorubin B

The enantioselective total synthesis of the pyrrolophane natural product streptorubin B is described. Key steps in the concise route include the application of a one-pot enantioselective aldol cyclization/Wittig reaction and an anionic oxy-Cope rearrangement to forge the crucial 10-membered ring. Comparisons between CD spectra of synthetic and natural samples of streptorubin B coupled with X-ray crystallography allowed for the determination of the absolute stereochemistry of this natural product for the first time. These studies also provided unambiguous proof of the relative configuration between the butyl side chain and the bispyrrole subunit. Additional studies revealed a novel atropstereoselective Paal-Knorr pyrrole condensation and provided fundamental experimental insight into the barrier for atropisomerization of the natural product.

Photoinduced cytotoxicity and thioadduct formation by a prodigiosin analogue

(Chemical Equation Presented) The prodigiosin alkaloid 1 and the synthetic analogue 2 show photoinduced cytotoxicity against HL-60 cancer cells.

Synthesis and antimicrobial activities of N-substituted imides

In the field of our research programs concerning novel antimicrobial agents, a series of N-substituted imides was synthesized. These compounds were obtained by cyclization of amido-acids in acetic anhydride/sodium acetate or hexamethyldisilazane/zinc bromide for the hydroxy-aromatic derivatives. The hydroxy-alkyl maleimides were directly prepared by condensation of the corresponding amino-alcohol with maleic anhydride in boiling toluene. Most of N-substituted maleimides showed an interesting antimicrobial activity towards bacteria from the ATCC collection (Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853) but the MIC values for P. aeruginosa were always high (128 mug/ml). The imides with alkyl substituents showed higher activities than aromatic analogues with MIC values in the range of 8-32 mug/ml. Comparatively, succinimides were practically inactive.

Synthetic Transformations of Higher Terpenoids: VIII.* [4+2]-Cycloaddition Reactions of Lambertianic Acid

The Diels-Alder reaction of lambertianic acid with maleic anhydride occurred in a stereoselective fashion and yielded diastereoisomeric (1R,2S,6R,7R)- and (1S,2R,6S,7S)-exo-adducts. The latter reacted with L-valinol to give the corresponding diterpenoid imides, 4-aza-9-oxabicyclo[2.2.1]dec-8- enes. Reactions of lambertianic acid with N-substituted maleimides in the presence of Lewis acids afforded diastereoisomeric adducts having both exo and endo configuration. Some transformations of the adducts were examined with a view to obtain cantharidin and dihydroisoindole analogs.

Palladium-catalyzed difunctionalization of enol ethers to amino acetals with aminals and alcohols

A new strategy was developed for intercepting the palladium-alkyl species generated in Heck reaction via nucleophilic addition prior to the step of migratory insertion, which leads to a new palladium-catalyzed difunctionalization of enol ethers with aminals and alcohols to afford amino acetals. Mechanistic studies suggested that the cationic cyclometalated Pd(II) complex generated by the oxidative addition of aminal to a Pd(0) species was crucial for this unusual transformation.
