Synthesis of acyclic polyol derivatives via enzyme-mediated aldol reaction
摘要:
Enzyme-mediated stereoselective aldol reaction between dihydroxyacetone phosphate (DHAP, 1) and (2R,4R)-6-benzyloxy-2,4-dimethoxyhexanal (8) was catalyzed by rabbit muscle aldolase (RAMA) to generate (3S,4R,5R,7R)-trihydroxyketone 12, which could be easily transformed to the masked polyhydroxylated compound 15 corresponding to the C-9 approximately C-16 segment of pentamycin (6).

A stereoselective and convergent approach to the total synthesis of the natural product passifloricin A is illustrated using Prins cyclisation and metathesis reactions as key steps.
