Ansalactam A is an ansa macrolide natural product that contains a densely functionalized spiro-γ-lactam core containing three contiguous stereocenters. This unusual motif distinguishes it from other members of this family and represents a significant synthetic challenge. Herein, we report the development of a stereoselective formal [3+2] cycloaddition reaction for the construction of this key spiro-γ-lactam motif for the first time, thereby enabling access to the northern domain of ansalactam A.

An efficient, flexible, and stereoselective convergent route for constructing the trans-10-hydroxy-1,1-dimethyloctahydrodibenzo[a,d]cyclohepten- 7-ones (5a-c) was achieved via intramolecular Heck reaction. This strategy has been successfully implemented for the syntheses of (±)-komaroviquinone (3) through (±)-coulterone dimethyl ether (5c) and (±)-faveline methyl ether (1a).
