(S)-6-Chloro-4-cyclopropylethynyl-4-trifluoromethyl-1H-3,1-benzoxazin-2(4H)-one
Two independent molecules comprise the crystallographic asymmetric unit in the title antiretroviral agent Efavirenz, C14H9ClF3NO2, and these have noteworthy differences in conformation. The major difference relates to the orientation of the 2-cyclopropylethynyl residue relative to the six-membered h...
