The synthesis of chiral aminoalcohols 4 derived from (S)-tryptophan is described, by reaction of the protected amino acid 3 with various Grignard reagents. The aminoalcohols were transformed into the corresponding oxazolidin-2-ones 2 and acylated with 2-butenoyl chloride and 2-hexenoyl chloride, affording the imides 5a-e. The conformational analysis of both the oxazolidin-2-ones 2 and the Michael acceptors
通过受保护的氨基酸3与各种格氏试剂的反应,描述了衍生自(S)-色氨酸的手性氨基醇4的合成。将氨基醇转化成相应的恶唑烷-2-酮2,并用2-丁烯酰氯和2-己烯酰氯酰化,得到酰亚胺5a-e。通过1 H NMR,NOEDIF实验和半经验AM1计算,对恶唑烷-2-酮2和迈克尔受体5进行构象分析。
