Total Svntheses of (±)-N-Nordasycarpidone and (±)-Dasycarpidone (Studies on the Syntheses of Heterocyclic Compounds. CDXVIII)

Abstract

The stereoselective total syntheses of (±)-N-nordasycarpidone (I) and (±)-dasycarpidone (II) are herein described. The key step in the approach to these syntheses involved cis addition with catalytic reduction of a hydrochloride (VIII).
