A straightforward synthesis of L-azetidine-2-carboxylic acid is described, leading to both orthogonally protected versions or totally deprotected L-Aze. The starting material is a commercially available aspartic acid derivative, whose chirality is conserved. The (2-trimethylsilyl)ethanesulfonyl protecting group (SES) acts as a leaving group on the hydroxy function and serves as an activator for the
描述了 L-氮杂环丁烷-2-羧酸的直接合成,导致正交保护的版本或完全脱保护的 L-Aze。起始材料是市售的天冬氨酸衍生物,其手性是守恒的。(2-三甲基甲硅烷基)乙磺酰基保护基团 (SES) 作为羟基官能团的离去基团,并作为胺官能团的活化剂,这是反应的关键步骤。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
