  Versatile synthesis of quaternary 1,3-oxazolidine-2,4-diones and their use in the preparation of α-hydroxyamides

  摘要：

  A new approach to the synthesis of 1,3-oxazolidine-2,4-diones, via a two-step reaction sequence, starting from the readily available alpha-ketols and isocyanates, is reported. The condensation of the latter led to the key precursors 4-methylene-2-oxazolidinones, which are converted into the diones by an oxidative cleavage of the exocyclic double bond. Thus, 5,5-disubstituted 1,3-oxazolidine-2,4-diones can be accessed in good yields from the appropriate functionalized alpha-ketols. Moreover, two alternative routes are also described either by functionalization of 4-oxazolin-2-ones or by alkylation of the 1,3-oxazolidine-2,4-dione core previously prepared. Upon hydrolysis of the 1,3-oxazolidine-2,4-diones, a series of alpha-hydroxyamides bearing a quaternary stereocenter were obtained. (C) 2010 Elsevier Ltd. All rights reserved.

  Palladium-catalyzed functionalization was presently performed on two building blocks: 4-oxazolin-2-ones and 4-methylene-2-oxazolidinones. Direct Heck arylation of 4-oxazolin-2-ones led to a series of 5-aryl-4-oxazolin-2-ones, including analogues with N-chiral auxiliary, in an almost quantitative yield. The Pd(II)-catalyzed homocoupling reaction of 4-oxazolin-2-ones provided novel heterocyclic across-ring

  A monomeric magnesium compound was employed as a catalyst for the cascade cyclization of propargylic alcohol and isocyanate, resulting in the formation of pharmaceutically significant oxazolidinone derivatives. This transformation, previously attributed solely to transition metals or lanthanides, signifies a noteworthy advancement.
