N, N, N -Triphenylselenylisocyanuric Acid (TPSCA): A New Versatile Reagent for α-Phenylselenenylation of Aldehydes and Ketones

A new, versatile reagent, N,N,N-triphenylselenyl-isocyanuric acid (TPSCA) has been prepared, characterized, and used as a source of the electrophilic phenylselenyl group. This relatively stable compound was utilized for an efficient α-selenenylation react

ORGANOCATALYSTS AND METHODS OF USE IN CHEMICAL SYNTHESIS

The present invention pertains generally to compositions comprising organocatalysts that facilitate stereo-selective reactions and the method of their synthesis and use. Particularly, the invention relates to metal-free organocatalysts for facilitation of stereo--selective reactions, and the method of their synthesis and use. These compounds have the structure of the Formulas (I) and (II). Where X is independently selected from CH2, N-Ra, O, S or C=O; Y is CH2, N-Ra, O, S or C=O, with the proviso that at least one of X or Y is CH2, and preferably both of X and Y are CH2; Ra is H, an optionally substituted C1-C12 alkyl, preferably an optionally substituted C1-C6alkyl including a C3-C6 cyclic alkyl group, or an optionally substituted aryl group, preferably an optionally substituted phenyl group; Rb is H, an optionally substituted C1-C12 alkyl, preferably an optionally substituted C1-C6 acyclic or a a C3-C6 cyclic alkyl group, CHO, N(Me)O, CO(S)Ra or the group of Formula (III). Where Rc and Rd are each independently H, F, C1, an optionally substituted C1-C20 alkyl, preferably an optionally substituted C1-C12 alkyl, more preferably a C1-C6 alkyl, and an optionally substituted aryl group, or together Rc and Rd form an optionally substituted carbocyclic or optionally substituted heterocyclic ring; R1 is OH, OR, NR'R", NHC(=O)R, NHSO2R; R2 is H, F, C1, an optionally substituted C1-C20 alkyl, preferably an optionally substituted C1-C6 alkyl, an optionally substituted aryl group or a =O group (which establishes a carbonyl group with the carbon to which =O is attached; R3 is H, OH, F, C1, Br, I, Cl, an optionally substituted C1-C20 alkyl, alkenyl or alkynyl ("hydrocarbyl") group, preferably an optionally substituted C1-C6 alkyl, or an optionally substituted aryl, such that the carbon to which R3 is attached has an R or S configuration; R is H, an optionally substituted C1-C20 alkyl, preferably an optionally substituted C1-C6 alkyl, or an optionally substituted aryl group, R' and R" are each independently H, an optionally substituted C1-C20 alkyl group, preferably an optionally substituted C1-C6 alkyl, or an optionally substituted aryl group; or together R' and R" form an optionally substituted heterocyclic, preferably a 4 to 7 membered optionally substituted heterocyclic group or an optionally substituted heteroaryl ring with the nitrogen to which R' and R" are attached; and wherein said compound is free from a metal catalyst.

Direct, facile aldehyde and ketone α-selenenylation reactions promoted by L-prolinamide and pyrrolidine sulfonamide organocatalysts

A new catalytic method for direct α-selenenylation reactions of aldehydes and ketones has been developed. The results of exploratory studies have demonstrated that L-prolinamide is an effective catalyst for α-selenenylation reactions of aldehydes, whereas

A simple and efficient L-prolinamide-catalyzed α-selenenylation reaction of aldehydes
