alcohols were synthesised by an improved procedure based on ring opening of 2-tributylstannyloxazolidines. Corresponding α-amino organolithiums were generated from O-silylated tributylstannylated α-amino alcohols and trapped with retention of configuration. Thereby, this methodology was used to synthesise the antibacterial α-aminophosphonic acid alafosfalin.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
对映体富集的三丁基甲锡烷基化 α-氨基醇是通过基于 2-三丁基甲锡基恶唑烷开环的改进程序合成的。相应的 α-氨基有机锂由 O-甲硅烷基化的三丁基甲锡烷基化的 α-氨基醇生成,并在保留构型的情况下被捕获。因此,该方法用于合成抗菌α-氨基膦酸alafosfalin。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
