Abstract
Abstract 1, 5-Bis(trimethylsiloxy)-1, 5-dimethoxy-1, 4-pentadienes ( 7 ) can be prepared in good yield by silylation of the dianions of dimethyl glutarates ( 8 ). On treatment with titanium tetrachloride, 7 cyclise stereoselectively to dimethyl trans -cyclopropane-1, 2-dicarboxylates 10 . Reaction of 7 with acetic anhydrode and titanium tetrachloride gives substituted cyclobutanes 22b–d .
