  a general process for the in situ generation of diazo compounds from tosylhydrazone sodium salts has been established and applied in sulfur-ylide mediated epoxidation reactions. The chiral, camphor-derived, [2.2.1] bicyclic sulfide 7 was employed (at 5-20 mol % loading) to render the above processes asymmetric with a range of carbonyl compounds and tosylhydrazone sodium salts. Benzaldehyde tosylhydrazone

  已经制备了多种衍生自苯甲醛的金属化甲苯磺酰腙盐，并在四氢噻吩 (THT) (20 mol %) 和 Rh(2)(OAc)(4) (1 mol %) 存在下与苯甲醛反应，得到二氧化二苯乙烯. 在所测试的锂盐、钠盐和钾盐中，发现钠盐的产率和选择性最高。该研究扩展到各种芳香族、杂芳香族、脂肪族、α、β-不饱和和乙炔醛以及酮。总的来说，观察到具有中等至非常高的非对映选择性的环氧化物的高产率。还使用相同的方案在与苯甲醛的反应中检查了衍生自芳香族、杂芳香族和 α,β-不饱和醛的范围广泛的甲苯磺酰腙盐，再次，在大多数情况下观察到良好的产率和高的非对映选择性。因此，已经建立了从甲苯磺酰腙钠盐原位生成重氮化合物的一般方法，并将其应用于硫-叶立德介导的环氧化反应。使用手性、樟脑衍生的 [2.2.1] 双环硫化物 7（以 5-20 mol% 负载量）使上述过程与一系列羰基化合物和甲苯磺酰腙钠盐不对称。苯甲醛甲苯磺酰腙钠盐提供

  A method for making diazo-compounds, diazonium salts thereof and other protected forms of these compounds. Diaz-compounds are prepared by reaction of a tertiary phosphine reagent carrying a reactive carbonyl group with an azide. The reaction can also generate an acyl triazene which can be converted thermally or by addition of base to form the diazo-compound or the acyl triazene can be isolated. The method is particularly useful for conversion of azides carrying one or more electron withdrawing groups to diazo-compounds. The method can be carried out in aqueous medium under mild conditions and is particularly useful for conversion of azido sugars to diazo-compound and diazonium salts thereof under physiological conditions. Tertiary phosphine reagents, particularly those that are water-soluble, and precursors for preparation of the reagents are provided.
