Stereocontrolled aldol additions to α-methylene-β-alkoxy aldehydes: Application to the synthesis of a C13C25 segment of bafilomycin A1
摘要:
A boron-mediated, syn-aldol coupling between ethyl ketone 8 and aldehyde 9, followed by directed hydrogenation at C-16 and acetonide hydrolysis, gives the C-13-C-25 segment 6 of bafilomycin A(1).
