摘要：

Reaction of 2-ethoxy-2-methyl-l, 3-dioxolan (lc) with 1-methoxy-l-trimethylsilyloxyethene (4a) in dichloromethane in the presence of titanium tetrachloride gave 62% of methyl 2-(2′-methyl-l′, 3′-dioxolan-2′-yl)acetate (5a). Similarly, reaction of (lc) with 1-methoxy- 1-trimethylsilyloxyprop-l-ene (4b) afforded 73% of methyl 2-(2′-methyl-l′, 3′-dioxolan-2′- y1)propanoate (5b). © 1990 ASEG.
