  Two-Step Synthesis of Difluoromethyl-Substituted 2,3-Dihydrobenzoheteroles

  摘要：

  3-Difluoromethylated 2,3-dihydrobenzoheteroles, 2,3-dihydrobenzofurans, 2,3-dihydrobenzothiophenes, and indolines were readily synthesized from ortho-heterosubstituted bromobenzenes, 2-bromophenols, 2-bromobenzenethiols, and 2-bromoanilines, respectively, in two steps: (1) gamma-selective allylic substitution of 3-bromo-3,3-difluoropropene with heteronucleophiles and (2) intramolecular radical cyclization of the resulting 3,3-difluoroallylic compounds.
