Highly enantioselective amide ligation by prior thiol capture
摘要:
The mixed disulfides from (R,S)-1-(Cbz-L-alanyloxy)-9-mercapto-phenoxathiin-10-sulfoxide and H-L-Cys-OMe undergo O,N-acyl transfer in DMSO at 23-degrees-C with rate constants of 7.0 h-1 and 0.048 h-1, and a rate ratio of 146; EM values of 0.2 M and 0.0015 M.
