Unified Total Syntheses of (−)‐Medicarpin, (−)‐Sophoracarpan A, and (±)‐Kushecarpin A with Some Structural Revisions

Abstract

The total syntheses of medicarpin, sophoracarpan A, and kushecarpin A from a common intermediate are achieved by using ortho- and para-quinone methide chemistry. Additionally, the relative stereochemistry of sophoracarpan A and B have been reassigned.
