摘要：

A marked opening of two opposite bond angles characterizes the title compounds 1 and 2 (R = CO2Et). One strategy for widening the bond angle is the generation of trans‐bicyclo[3.3.0]octane subunits. This has now been achieved for the first time by a [2 + 2] cycloaddition at the endo side of a bicyclo[3.3.0]oct‐l‐en‐3‐one. (Figure Presented.)
