Abstract: (Matrix presented) Poor stereoselectivity caused by the involvement of side reaction pathways was observed in the In(OTf)3-catalyzed allyl-transfer reaction (R = electron-withdrawing group). Subsequently, it was found that the employment of triflic acid (TFA) as catalyst could successfully suppress the side reaction pathways and, hence, achieve high stereoselectivity.
