PROCEDURE

实验过程

A solution of 110 mg (0.5 mmol) of trans-1,2-diacetoxy-1,2-dihydrobenzocyclobutene and 112 mg (0.35 mmol) of rac-3-acetoxy-3-acetyl-1,1-ethylenedioxy-1,2,3,4,5,8-hexahydro-5,8-dioxonaphthalene in 10 ml of toluene was stirred and heated under reflux for 3 hours under an atmosphere of nitrogen. The solution was evaporated and the resulting yellow gum was crystallised from diethyl either to yield 80 mg (42%) of rac-3,6,11-triacetoxy-3-acetyl-1,1-ethylenedioxy-1,2,3,4,5,5a,6,11,11a,12-decahydro-5,12-dioxonaphthacene in the form of a pale yellow solid of melting point 133°-143° C.
