  Oxyoxazolidinone as an auxiliary for heterocyclic synthesis. Enantioselective formation of N-unprotected 2-pyrrolidones from selenocarboxylate and allylamines via radical cyclization

  摘要：

  Optic ally active N-unprotected 2-pyrrolidones were prepared in a highly stereoselective manner through radical cyclization reaction of oxyoxazolidinone. Asymmetric induction from the oxyoxazolidinone ring system was generally high and oxazabicyclo[3.3.0]-octanones were obtained in good yields. Treatment of the bicyclic compounds with TBAF resulted in the one-step cleavage of C-O and C-N bond. directly giving secondary 2-pyrrolidones in good yields along with recovery of chiral mandelic acid without loss of optical purity. The use of the present procedure gave optically active 4,5-disubstituted N-unprotected 2-pyrrolidone derivatives trans selectively. (C) 2003 Elsevier Ltd. All fights reserved.

  双钯（II）/叔胺催化烯丙基氨基甲酸酯的不对称区域选择性重排

  摘要：

  简化的对映纯制取对映纯烯丙基胺作为手性β-和γ-氨基醇以及α-和β-氨基酸的有价值的前体，对于工业目的是理想的。本文介绍了一种对映选择性方法，该方法可将非手性烯丙基醇和N-甲苯磺酰基异氰酸酯一步转化为高度对映体富集的N甲苯磺酰基通过氨基甲酸酯氨基甲酸酯中间体保护的烯丙基胺。后者很可能会发生环化诱导的[3,3]重排，该反应是由平面手性五苯基二茂铁戊四环与叔胺碱共同催化的。在当前情况下，不需要通过银盐进行原本通常不可缺少的帕拉达环催化剂的活化，并且也不需要惰性气体气氛。为了进一步提高合成值，重排用于形成二甲基氨基磺酰基保护的烯丙基胺，可以在非还原条件下将其脱保护。

  High yielding and highly diastereoselective methods for 1,2-additions of organometallic reagents to N-tert-butanesulfinyl aldimines (2) and N-tert-butanesulfinyl ketimines (3) are described. The additions of alkyl, aryl, alkenyl, and allyl carbanions to a diverse set of imines with different steric and electronic properties are demonstrated.

  access to enantiopure allylic amines as valuable precursors towards chiral β‐ and γ‐aminoalcohols as well as α‐ and β‐aminoacids is desirable for industrial purposes. In this article an enantioselective method is described that transforms achiral allylic alcohols and N‐tosylisocyanate in a single step into highly enantioenriched N‐tosyl protected allylic amines via an allylic carbamate intermediate
