  A new and expeditious strategy for the synthesis of β-amino acids from Δ2-oxazolines

  摘要：

  A new, mild two-step synthesis of racemic p-amino acids starting from 2-allkyl-Delta (2)-oxazolines is described. The process implies the initial formation of masked N-substituted or N-unsubstituted beta -enamino acid derivatives followed by chemoselective reduction of the enamino moiety. The process takes place with high yields, total chemoselectivity and moderate diastereoselectivity. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Various heterocycles 3a-h can be readily metallated and condensed with a variety of organic nitriles to afford C-protected beta-enamino acid derivatives 1 (or 2). Procedures for alkylation of compounds 1 to obtain 2 as well as a "one-pot" preparation of 2 from 3 are also described. (C) 1999 Elsevier Science Ltd. All rights reserved.

  An efficient a rid convenient synthesis of new fluorinated a rid non-fluorinated uracils is described herein. The condensation of nitriles with enolates generated from 2-alkyl-Delta(2)-oxazolines affords fluorinated beta-enamino acid derivatives, which react with triphosgene to give an isomeric mixture of oxazolopyrimidinones. These can then be easily transformed into a single C-6 pyrimidindione derivative through reaction with a suitable nucleophile. (c) 2008 Elsevier B.V. All rights reserved.
