different stabilized diazo compounds is reported. Studies on the reactivity of the condensation products have been undertaken, finding out novel transfromations of β-oxy-α-diazo carbonyl compounds with sinthetic applications. Thus, a stereoselective Wolff rearrangement provided syn 2-hydroxy-1-methyl compounds, which represent macrolide type structural subunits. On the other hand, rhodium (II) mediated rearrangements
报道了单糖衍生物与不同的稳定化的重氮化合物的反应。已经进行了缩合产物反应性的研究,发现了在合成中β-氧基-α-重氮羰基化合物的新型转化。因此,立体选择性Wolff重排提供了代表大环内酯型结构亚基的顺式2-羟基-1-甲基化合物。另一方面,铑(II)介导的衍生自单糖的β-乙酰氧基-α-重氮羰基化合物的重排导致天然醛糖酸KDG和DAH的有效合成。
