The zwitterionic species generated by the addition of dimethoxy carbene to dimethyl acetylenedicarboxylate (DMAD) is trapped by aldehydes and quinones to yield dihydrofuran derivatives in good yields.
Novel Dipolar CycloadditionReactions of Zwitterionic Species Generated from Dimethoxycarbeneand Dimethyl Acetylenedicarboxylate with Carbonyl Compounds: FacileSynthesis of Dihydrofuran Derivatives
The reaction of 1:1 zwitterionic species, generated in situ by the addition of dimethoxycarbene to dimethyl acetylenedicarboxylate, towards carbonyl compounds is described. The reactions presented offer a one-pot synthesis of dihydrofuran and spiro dihydrofuran derivatives in high yields.
