摘要

The carbenoid intermediate derived by treating ethyl 2-diazo-4-phthalimidobutyrate with rhodium (I1) octanoate undergoes transannular cyclization onto the adjacent imido carbonyl group. The resulting cyclic carbonyl ylide dipole was trapped with several dipolarophiles. In an attempt to prepare related substrates for cyclization studies, the reaction of ethyl lithiodiazoacetate with various aldehydes and ketones was studied. Treatment of the a- ...
