Friedel–Crafts alkylation of natural amino acid-derived pyrroles with CF3-substituted cyclic imines
摘要:
Natural amino acid-derived ethyl 2-(1-pyrrolyl)alkanoates react with 2-trifluoromethyl-1-azacycloalkenes selectivity at the P-position of the pyrrole moiety to afford ethyl 2[3-(1-trifluoromethyl-2-azacycloalkyl)pyrrol-1-yl]alkanoates.
