Abstract
The 3-methoxy-7-methyl-4b,5,6,8a,9,10-hexahydro-6, 8a-ethanophenanthrenes (2) and (26), potential inter-mediates for the synthesis of isoatisirene (1), have been synthesised by using an intramolecular cycloaddition reaction of the o-quinodimethan (5), which was itself derived thermally from 5-mehoxy-1-(2-methyl-3-oxo-4-phenylthiomethylenecyclohexylmethyl)-1, 2-dihydrocyclobutabenzene (17).Keywords
