• Intramolecular Schmidt reactions of alkyl azides with ketals and enol ethers

  The ketals or enol ethers of 1,5-azidoketones were converted into lactams using a two-stage process. Treatment of the ketals and enol ethers with acid (trifluoroacetic acid, triflic acid, or trimethylsilyl triflate) afforded an oxonium ion which reacted with the tethered azide to give a 1,1-azido-alkoxy intermediate. Bond reorganization led to an iminium ether that was reacted with sodium iodide in

  使用两步法将1，5-叠氮酮的缩酮或烯醇醚转化为内酰胺。用酸（三氟乙酸，三氟甲磺酸或三甲基三氟甲磺酸酯）处理缩酮和烯醇醚，得到氧鎓离子，其与束缚的叠氮化物反应，得到1，1-叠氮基-烷氧基中间体。键的重组产生了亚胺醚，该亚胺醚与碘化钠在丙酮中反应以暴露出酰胺产物。据报道，使用二甲基或二乙基缩酮，有七个分子内实例的收率在68％至≥95％之间。还描述了使用1，3-二氧戊环的尝试和一个分子间的实例。
• Intramolecular Schmidt Reactions of Alkyl Azides with Ketones: Scope and Stereochemical Studies

  The intramolecular Schmidt reaction of alkyl azides and ketones has been demonstrated. The reaction is proposed to occur via initial attack of an azide on a ketone activated by a variety of protic or Lewis acids, including trifluoroacetic acid, titanium tetrachloride, and others. The resulting azidohydrin undergoes a direct rearrangement to afford the product amide and molecular nitrogen. When cyclic ketones are used, fused bicyclic lactams of types encountered in a wide variety of natural products are obtained. Although the distance allowed between the carbonyl group and the alkyl azide is quite restricted, the reaction is general with respect to the ketone component, including acyclic ketones and cyclic substrates ranging from standard to large ring sizes. The reaction also succeeds with aldehydes, although elimination or hydride migration products compete. In several cases examined, the reaction was found to proceed with retention of configuration at the migrating carbon. Competing reactions with beta-diketones and alpha,beta-unsaturated ketones were found to predominate over ring expansion.
