Abstract
4,8-Dimethyl-1,4,5,6,7,7a-hexahydroinden-2-one (7), obtained by Wichterle annelation of 2,6-dimethylcyclohexanone, was converted into 1-hydroxy-5,8-dimethyl-1,7,8,9-tetrahydro-3H-2-benzopyran-3-one (26). Treatment of compound (26) with 3-lithiofuran afforded pyroangolensolide (1) together with its diastereoisomer (4).Keywords
