The unique biological activity of pyrrolidine compounds has attracted significant interest from medicinal chemists. This study presents a one-step synthesis of [indolyl-3,2'-pyrrolidine] compounds with three chiral centers and an α-CF3 group in excellent yields and enantioselectivities by reacting trifluoroethyl ketoimine with unsaturated alkynyl ketone compounds through a chiral guanidine catalized [3+2] cycloaddition reaction. The mild reaction condition, low catalyst loading and high reaction rate make this synthetic method highly attractive for pharmaceutical synthesis.
