novel routes have been developed for the synthesis of 2-amino-4-hydroxycyclohexanecarboxylic acid and its 3-hydroxy-substituted analog via iodooxazine, iodooxazoline or iodolactone intermediates. After CAL-B-catalyzed enzymatic transformation of the starting β-lactam, the iodolactone method was applied to the synthesis of 3-hydroxy-substituted β-amino acid enantiomers.

从 cis-7-azabicyclo[4.2.0]oct-4-en-8-one 开始,已经开发了通过碘恶嗪合成 2-氨基-4-羟基环己烷甲酸及其 3-羟基取代的类似物的新路线,碘恶唑啉或碘内酯中间体。在 CAL-B 催化酶促转化起始 β-内酰胺后,碘内酯法用于合成 3-羟基取代的 β-氨基酸对映异构体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
