  Syntheses and rearrangements of spirocyclic oxaziridines derived from unsymmetrical ketones

  摘要：

  Oxaziridines provide useful alternatives to the Beckmann rearrangement and Schmidt reaction for ring enlargement of cyclic ketones. The procedure involves the condensation of the ketone in question with optically active alpha-methylbenzylamine, oxidation of the resultant imine, and photolysis to afford ring-expanded lactams. The alpha-phenylethyl substituent can be removed after photolysis to yield the N-unsubstituted lactam. When a distal ketone substituent is present, the oxaziridines can be synthesized stereoselectively. Thus, optically active ketones can be converted to either ring-expanded lactam by choice of either enantiomer of optically active alpha-methylbenzylamine. Ketones bearing adjacent substitution are generally not amenable to such regiocontrol because the resident substituent is the key stereocontrol element for the oxaziridine synthesis, although a notable exception is 2-methoxycyclohexanone. Stereogenic centers present in such compounds undergo epimerization during the couse of the reaction sequence; in addition, substrates containing substantial amounts of enamine give rise to novel doubly oxygenated products upon oxidation. Finally, the conformational behavior of the side chains in both oxaziridines and their product lactams permits some key stereochemical assignments to be made, on the basis of chemical shift trends in the NMR spectra of these materials.

  ketone decomposition products with loss of the chain-carrying tributyltin radical. The noteworthy occurrence of a quite uncommon radical 1,2-hydrogen-atom shift is considered to be largely due to consequent formation of a highly stable, captodative carbon-centred radical. In contrast with our previous N-stannylaminyl radicals produced from α-azido-β-keto esters, the present aminyl congeners give poor

  研究了各种无环和环状α-叠氮基酮与氢化三丁基锡的自由基链反应。衍生的N-（三丁基锡烷基）氨基自由基通常会发生H吸收反应，生成相应的胺，因此通过随后的自缩合反应形成对称的吡嗪，与从α碳到氮的1,2-H迁移竞争，从而导致α-亚氨基酮的分解产物，带有链的三丁基锡自由基的损失。值得注意的是，一个非常不常见的自由基1,2-氢原子移位的发生在很大程度上是由于随后形成了一个高度稳定的，可俘获的碳中心自由基。与我们以前的N相反α-叠氮基-β-酮酯产生的-stannylaminyl自由基，本发明的胺基同类物产生的氮插入酰胺/内酰胺的量很少（甚至根本没有），预计这是由于分子内三元环化到酮部分上而引起的通过β-断裂得到的烷氧基基团。可以推断，最终的开环碳自由基的足够稳定是区域特异性氮插入过程成功获得成功的主要因素。还提供了证据，三（三甲基甲硅烷基）甲硅烷基自由基对α-叠氮基酮的酮氧的化学选择性攻击导致脱叠氮化作

  Treatment of 3-phenylazetidin-2-one and 7-phenylazepin-2-one with triflic acid in benzene gave a novel, high yielding conversion to 3,3-diphenylpropionamide and 6,6-diphenylhexanoic acid amide, respectively. However, with AlCl3, 7-phenylazepin-2-one was converted into 3-phenylazepin-2-one via a retro-Beckman rearrangement. (C) 2011 Elsevier Ltd. All rights reserved.
