Stereoselective synthesis of pyrrolidines: catalytic oxidative cyclizations mediated by osmium.

Stereoselective synthesis of pyrrolidines: catalytic oxidative cyclizations mediated by osmium.

(Chemical Equation Presented) A new pathway for oxidative cyclization : N-protected α-amino alcohols with distal alkene units cyclize with complete stereoselectivity and stereospecificity to cispyrrolidines, dependent on the substitution pattern of the starting material. In addition to providing nit...
