Abstract

Abstract A fundamentally new approach was developed to designing pyrrole and dihydropyridine rings from available allenes and isothiocyanates involving a single preparative stage. Applying the reaction of lithiated alkoxyallenes with aliphatic isothiocyanates we have synthesized previously unknown 1-alkyl (cycloalkyl) pyrroles and 2, 3-dihydropyridines with rare alkoxy-and alkylsulfanyl substituents. It was proved that the ...
