摘要
An expedient and mild strategy for the synthesis of unconventional 2-（dimethylamino）-3,3-difluorochroman-4-one derivatives from o-hydroxyarylenaminones and Selectfluor was developed at room temperature under catalyst-free conditions. This method showed excellent chemoselectivity and great functional groups tolerance.
