Methoxyallene oxide was readily prepared in situ by epoxidation of methoxyallene with 3-chloroperbenzoic acid, and the subsequent reaction with aldehydes or acetals was promoted by titanium tetraiodide and additives to give 2,3-dialkoxy- or 3-hydroxy-2-methoxy ketones in good yields.
甲氧基丙烯与3-氯过苯甲酸环氧化可容易地就地制备甲氧基丙二烯氧化物,随后通过四碘化钛和添加剂促进与醛或乙缩醛的反应,得到2,3-二烷氧基或3-羟基-2-甲氧基酮。良品率高。
