Pure 3-L-chlorotyrosine-[ring-13C6] is prepared by chlorination of the 5-oxazolidinone of L-tyrosine-[ring-13C6] with SO2Cl2 in CH3COOH-Et2O and successive one-pot regeneration of the protected aminoacidic functions by BCl3 in dichloromethane. Copyright © 2004 John Wiley & Sons, Ltd.
纯净的 3-L-氯酪氨酸[环-13C6]是通过在 CH3COOH-Et2O 中用 SO2Cl2 对 L-酪氨酸[环-13C6]的 5-噁唑烷酮进行氯化,然后在二氯甲烷中用 BCl3 对受保护的氨基酸官能团进行连续的单锅再生而制备的。Copyright © 2004 John Wiley & Sons, Ltd. All Rights Reserved.
