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
A novel method for the synthesis of α-amino alkenyl-substituted hydrazone derivatives was disclosed through silver-catalyzed reaction of sulfonyl hydrazones with ynamides. The present method features mild conditions, highstereoselectivity and good yields. The proposed mechanism involves silver-mediated generation of a keteniminium ion intermediate to facilitate the stereoselective addition of hydrazones
通过银催化磺酰与乙酰胺的反应,公开了一种合成α-氨基烯基取代的derivatives衍生物的新方法。本方法具有温和的条件,高的立体选择性和良好的收率。所提出的机理涉及银介导的酮亚胺离子中间体的产生,以促进在K 2 CO 3存在下立体选择性地添加,而在当前条件下不能构建吡唑环。
Direct Access for the Regio- and Stereoselective Synthesis of <i>N</i>-Alkenylpyrazoles and Chromenopyrazoles
A highly regio- and stereoselective method was developed for the preparation of N-alkenylpyrazoles and chromenopyrazoles by the reaction of N-tosylhydrazones and salicyl N-tosylhydrazones with alkynes under neat conditions in the presence of La(OTf)3. The present study was found to be efficient and convenient for direct access to N-alkenylpyrazoles and chromenopyrazoles through C–C, C–N, and C–O bond

We have developed a novel and efficient method for the oxidation of aryl sulfonylhydrazones to N-aroyl-N′-acyl arylsulfonylhydrazides, using hypervalentiodine (III) reagent in good yields at room temperature.
