Sodiumcyanoborohydride in trifluoroaceticacid selectively reduced the C5-orn and C4-htyr carbinols to methylene groups in echinocandin lipopeptides. The selective reduction of either hydroxyl is also described. The first conversion of echinocandin B to echinocandin C was accomplished.

dipeptide building block with fully elaborated N‐acyl hemiaminal proved to be a versatile precursor for echinocandin C, a prototypical member of the echinocandin group of antimycotic drugs. This first totalsynthesis of an N‐acyl hemiaminal‐containing echinocandin is concise and highly convergent, thereby making additional derivatives easily accessible. PG=protecting group.
