Vi. Dyachenko et al., SYNTHESIS OF ROXYPHENYL)-BETA,BETA,BETA-TRIFLUORO-ALPHA-ALANINE DERIVATIVES, Russian chemical bulletin, 43(9), 1994, pp. 1543-1545
2,6-Dimethyl- and carbonyl-alpha-trifluoromethyl-p-methylenequinones h
ave been synthesized. These compounds easily react with ammonia, morph
oline, and p-toluidine to afford the corresponding roxyphenyl)-beta,be
ta,beta-trifluoro-alpha-alanine derivatives.
