Conclusions
-
1.
The reduction of the activated cyclopropene double bond with lithium aluminum hydride is stereospecific and leads to alcohols of the cyclopropane series even at reduced temperatures. The reaction has a high degree of regioselectivity; initial attack by the hydride ion occurs at the oxygen atom adjacent to the methoxycarbonyl group.
-
2.
The reduction of functionally substituted methylenecyclopropane takes place either with retention of the exocyclic double bond or with its reduction, depending on the conditions.
