An efficient Brønsted acid-catalyzed asymmetricFriedel-Crafts alkylation of indoles with benzothiazole-bearing trifluoromethyl ketone hydrates as electrophiles has been developed. The mild organocatalytic reactions proceeded well with lowcatalystloading to afford a range of enantioenriched α-trifluoromethyl tertiary alcohols containing both benzothiazole and indole rings with excellent yields and

An efficient organocatalytic enantioselective cross-aldol reaction of aryl ketones with heteroaromatic trifluoromethyl ketone hydrates via enolate intermediates has been developed. The cross-aldol reactions catalyzed by Takemoto-type thiourea catalysts proceeded well under mild conditions, furnishing a variety of enantioenriched α-trifluoromethyl tertiaryalcohols bearing N-heteroaromatics with good
