Synthesis of both enantiomers of akolactone B and (+)-ancepsenolide
摘要:
The syntheses of (+)- and (-)-akolactone B and (+)-ancepsenolide were accomplished using a Pd-catalyzed carbonylation. As to the absolute configuration of akolactone B, making a comparison of the specific rotation of both enantiomers of synthetic akolactone B and the natural compound suggests that the absolute configuration at the 4-position of akolactone B is (R).
