  A scalable and expedient method of preparing diastereomerically and enantiomerically enriched pseudonorephedrine from norephedrine

  摘要：

  Norephedrine has been efficiently converted into the corresponding diastereomer pseudonorephedrine using a three step, one-pot reaction. The three step process involves treatment of norephedrine with di-tert-butyl dicarbonate (Boc(2)O); cyclization by way of mesylate formation at the alcohol; and lithium hydroxide mediated hydrolysis of the oxazolidinone. The diastereomeric purity was determined by HPLC and the enantiomeric purity was determined by optical activity measurements and chiral stationary phase HPLC analysis of the pseudonorephedrine oxazolidinone derivatives.

  Sulfonation of the N-Boc derivatives of 1,2-aminoalcohols, such as ephedrine, pseudoephedrine, norephedrine, norpseudoephedrine, thiomicamine, and chloramphenicol yields a mixture of the corresponding oxazolidinones with inversion (erythro derivatives) and/or retention of configuration (threo derivatives)at C5. We suggest a competition between two mechanisms: an intramolecular SN2 process initiated

  Treatment of N-tert-butoxycarbonyl derivatives of homochiral β-amino alcohols with p-toluenesulfonyl chloride affords 2-axazolidinones. These heterocycles were produced by intramolecular nucleophilic attack of the carbamate moiety in an intermediate tosylate. The presence of a N-methyl substituent enhanced the cyclization rate and this effect was studied by AM1 calculations.

  Carbon dioxide can be used as a convenient carbonylating agent in the synthesis of 2-oxazolidinones, 2-oxazinones, and cyclic ureas. The transient carbamate anion generated by treating a primary or secondary amine group in basic media can be activated with phosphorylating agents such as Diphenylphosphoryl azide (DPPA) and Diphenyl chlorophosphate (DPPCl) but also with other types of electrophiles such
