Abstract
Abstract Clemmensen reduction (zinc and hydrogen chloride in dry diethyl ether) of 1- methoxy-and 1, 5-dimethoxy-cyclohexa-1, 4-diene affords the cyclopropyl ethers, 1-methoxy- and 1, 5-dimethoxy-bicyclo [3.1. 0] hexane; in the presence of acetic anhydride, reduction of 6-acetyl-1-methoxy-6-methyl-cyclohexa-1, 4-diene leads regiospecifically to 7-acetoxy-1- methoxy-6, 7-dimethyl-bicyclo [4.1. 0] hept-4-ene.
