A novel, I2 catalyzed regio- and stereodivergent vicinal azidohydroxylation of alkenes leading to 1,2-azidoalcohols in high yields (up to 92%) and excellent dr (up to 98%) has been developed.
Concise Enantioselective Syntheses of (+)-L-733,060 and (2S,3S)-3-Hydroxypipecolic Acid by Cobalt(III)(salen)-Catalyzed Two-Stereocenter Hydrolytic Kinetic Resolution of Racemic Azido Epoxides
An efficient synthesis of the 2,3-disubstituted piperidines (+)-L-733,060 and (2S,3S)-3-hydroxypipecolic acid (99% ee) in high optical purity from commercially available starting materials is described. The strategy involves a cobalt-catalyzed hydrolytic kinetic resolution of a racemic azido epoxide with two stereocenters and an intramolecular reductive cyclization as key reactions.
