Indium-Mediated Reaction of 3-Bromo-3,3-difluoropropene and Bromodifluoromethylacetylene Derivatives with Aldehydes
摘要:
Aldehydes reacted with 3-bromo-3,3-difluoropropene at the a-position in the presence of indium to afford 1-substituted-2,2-difluorobut-3-en-1-ols. Ketones and other electrophiles are inert under the examined conditions. The reaction of bromodifluoromethyl-acetylene derivatives with an aldehyde in the presence of indium provided difluorohomopropargylic alcohols. These reactions efficiently proceeded in polar solvents (water, DMF) under mild conditions. (C) 2000 Elsevier Science Ltd. All rights reserved.
