By a com- bination of Me2Zn, Ti(OPr-i)4, BaF2 and quinine, the reaction of a series of terminal diynes with trifluoromethyl ke- tones proceeded to afford trifluoromethylated chrial tertiary alcohols with the diyne moiety in good to high yields with moderate to high enantioselectivities. Furthermore, this catalytic asymmetric diyne addition to trifluoro- methylketone was applied in the synthesis of the Efavirenz analogue.展开更多
