Synthesis of 3-(Thiazol-4-yl)alanine and 3-(Selenazol-4-yl)alanine Derivatives from Aspartic Acid^1-4 3-(Thiazol-4-yl)alanine as well as 3-(selenazol-4-yl)alanine and their derivatives can be obtained from aspartic acid, using hexafluoroacetone as protective group, via 2,2-bis(trifluoromethyl)-4-(3-bromo-2-oxopropyl)-1,3- oxazolidin-5-one (3) in a Hantzsch synthesis.
