2-Amino-2-(trifluoromethoxy)butanoic acid (O-trifluoromethyl homoserine) was synthesized as a racemate and in both enantiomeric forms. The measured pKa and log D values establish the compound as a promising analogue of natural aliphatic amino acids.

L-2-Amino-4-methoxy-trans-3-butenoic acid was isolated from a fermentation broth of Pseudomonas aeruginosa ATCC-7700. This substance inhibited the growth of Bacillus species 1283 B in a chemically defined medium. The growth inhibition was reversed by a variety of amino acids.
从铜绿假单胞菌 ATCC-7700 的发酵液中分离出 L-2-氨基-4-甲氧基-反式-3-丁烯酸。这种物质在化学定义的培养基中能抑制芽孢杆菌 1283 B 的生长。多种氨基酸可逆转这种生长抑制作用。

The wild type strain is able to hydrolyse water-soluble γ-alkoxyaminonitriles, under mild conditions, at pH value close to neutrality and at moderate temperature. The results reported here show that this technique is valuable for synthetic purposes.
