Synthesis of Propargylic Fluorides toward Carbo- and Heterocycles with Mono- and gem-Difluorinated Side Chains

摘要

This review reports the synthesis of propargylic derivatives with alkyl chains bearing either one fluorine or a gem-difluoro system. The preparation of the different categories of fluorinated derivatives is analyzed in a systematic manner, based on the nature of substituents close to the fluorine atom(s). In the second part of this review are summarized the synthetic applications of these fluorinated propargylic intermediates, focusing mainly on the preparation of carbo-and heterocyclic derivatives.
