摘要：

[2 + 2] cycloadditions of silyl enol ethers with dimethyl acetylenedicarboxylate, dimethyl fumarate, and methyl crotonate using titanium tetrachloride catalysis are reported. The cyclobutene adducts undergo a two-carbon ring expansion during acid hydrolysis. Copyright © 1979, American Chemical Society. All rights reserved.
