thiazole-containing amino acid (TCAA) has been established via a cascade disulfide cleavage/thiocarbonylation/intramolecular Staudinger reduction/aza-Wittig/oxidation reaction. Starting from the commercially available amino acid building blocks, a number of TCAAs were prepared in good yields and with excellent optical purities. This method bears features of mild reaction conditions, wide substrate adaptability
通过级联二硫键裂解/硫代羰基化/分子内斯托丁格还原/氮杂-维蒂希/氧化反应,已经建立了一种有效的一锅法,用于对映体合成含噻唑的氨基酸(TCAA)。从可商购的氨基酸构件开始,以高收率和优异的光学纯度制备了许多TCAA。该方法具有反应条件温和,底物适应性广,官能团耐受性好的特点。环状六肽Venturamides A和B的简明全合成也证明了该方法的强大功能。
