Abstract
A novel and facile strategy for stereoselective synthesis of new chiral (1R,4aR,8aR)‐1,3,4,4a,5,7,8,8a‐octahydro‐2‐methylenenaphthalene‐6‐one‐1‐propanenitrile (8) by one‐pot stereoselective hydrogenation/acetalization and Beckmann fragmentation is described. Chiral octalone 8, an important precursor of solanapyrone, was obtained in good yield.
