1-Phenyl-2-aza-3-trimethylsilyloxy-1,3-butadiene reacts with aliphatic, aromatic and cyclic ketones to give in good to excellent yields 6,6-disubstituted-1,3-perhydro-oxazin-4-ones which, in turn, have been readily converted into β-hydroxy carboxylic acids.
1-苯基-2-氮-3-三甲基硅氧基-1,3-丁二烯与脂肪酮、芳香酮和环酮反应,能够以良好至优异的产率得到6,6-二取代-1,3-过氢氧嗪-4-酮,而这些产物又可以容易地转化为β-羟基羧酸。
