摘要

Abstract Diastereomeric meso-and d, l-bis (bicyclopropylidenyl)(5) were obtained upon oxidation with oxygen of a higher-order cuprate generated from lithiobicyclopropylidene (4) in 50 and 31% yield, respectively. Their perdeuterated analogues meso-[D 14]-and d, l-[D 14]-5 were obtained along the same route from perdeuterated bicyclopropylidene [D 8]-3 (synthesized in six steps in 7.4% overall yield from [D 8]-THF) in 20.5% yield each. ...
