摘要: 在碳酸钾、丙酮的水溶液中由N-酰基四氢噻唑-2-硫酮进行氨基酸解得到10种N-酰基-α-氨基酸Ⅰa-j发现在三聚氯氰及三乙胺存在下,由N-酰基-α-氨基酸环合成8种饱和5(4H)-噁唑酮Ⅱa-h的新方法,进而在硫酸铁催化下得到10种不饱和5(4H)-噁唑酮衍生物Ⅲa-j

Abstract: In K2CO3-CH3COCH3-H2O system, N-acyl-a-amino acids (Ⅰa-j) were prepared by the reaction of amino acids with N-acyl thiazolidines-2-thiones and the yields were 76%~95%. The synthesis of saturated 5(4H)-oxazolones(Ⅱa-h) from Iunder mild reaction conditions in yields of 43%~84% by the use of cyanuric chloride as a condensing reagent in the presence of triethylamine was reported. Unsaturated 5(4H)-oxazolones (Ⅲa-j) were obtained from Iin the yields of 43%~93% by the aldol reaction in which Fe2SO4)3 was used as a catalyst.

Key words: N-acyl-a-amino acid, Cyanuric chloride, Saturated 5(4H)-oxazolone, Unsaturated 5(4H)-oxazolone
