dihydrofuroates 7a and 7b, respectively, which can be converted into the corresponding 2-(trifluoromethyl)pyrroles. This two step pyrrole synthesis is also suitable for the preparation of ethyl 2,3-bis(ethoxycarbonyl)-1H-pyrrole-1-propinate, an important intermediate for the synthesis of necin bases.
