The methyl analogue of Garner's aldehyde, N-tosyl-4-methyl-N,O-isobutyrylideneserinal, has been prepared in a one-step reaction by CuClO4-catalyzed aziridination of 2-isopropyl-5-methyl-4H-1,3-dioxin with N-tosyliminophenyliodinane and transformed into α-methylserine derivatives, e.g. α-vinylalanine.
在 CuClO4 催化下,2-异丙基-5-甲基-4H-1,3-二恶英与 N-对甲苯磺酰亚氨基苯基碘烷发生氮丙啶化反应,一步制备出了加纳醛的甲基类似物--N-对甲苯磺酰-4-甲基-N,O-异丁酰亚甲基丝氨酸醛,并将其转化为δ-甲基丝氨酸衍生物,如δ-乙烯基丙氨酸。
