WebThe trifluoromethyl group can be regarded as a classical isostere of nonpolar groups in proteinogenic α-amino acid side chains, namely, CH 3, SCH 3, CH (CH 3) 2, and CH 2 CH 3. Therefore, one can design a number of rigid trifluoromethyl-substituted amino acids to use as CF 3 -labels. However, it must be kept in mind that in a “good” CF 3 ...
