Methyl Acrylate → 1,2,3,4,5,12-Hexahydro-7,10-dimethoxy-5,12-epoxynaphthacene-2-carboxylic acid methyl ester

Participants

Reaction Steps

In a manner analogous to that described in Example 1, a mixture of 1,2,3,4-tetrahydro-5,8-dimethoxy-2,3-dimethylene-1,4-epoxyanthracene and methyl acrylate was reacted to give 1,2,3,4,5,12-hexahydro-7,10-dimethoxy-5,12-epoxynaphthacene-2-carboxylic acid methyl ester which was converted via 5,12-diacetoxy-1,2,3,4-tetrahydro-7,10-dimethoxy-2-naphthacenecarboxylic acid methyl ester into 5,12-diacetoxy-1,2,3,4,6,11-hexahydro-7,10-dimethoxy-6,11-dioxo-2-naphthacenecarboxylic acid methyl ester.
