A Novel Synthetic Approach to Isoatisirene-related Compounds via an Intramolecular Diels-Alder Reaction

A new synthesis of 2-oxo-18-norisoatisirene (2), a potential intermediate for the synthesis of isoatisirene (1), via 3-methoxy-7-methyl-9-phenylthio-4bβ,5,6,8a,9,10-hexahydro-6α,8aα-ethanophenanthren-8(7H)-one (4a) and 3-methoxy-7-methyl-7-phenylthio-4bβ,

A Simple Synthesis of a Basic Skeleton of Isoatisirene

The 3-methoxy-7-methyl-4b,5,6,8a,9,10-hexahydro-6,8a-ethanophenanthrenes (2) and (26), potential intermediates for the synthesis of isoatisirene (1), have been synthesised by using an intramolecular cycloaddition reaction of the o-quinodimethan (5), which
