Stereoselective synthesis of new monoterpene β-amino alcohols
摘要:
The regio- and stereoselective osmium-catalysed aminohydroxylation of (+)-2-carene (99% ee), and (+)-3-carene (99% ee), (-)-beta-pinene (99% ee) and (-)-camphene (75% ee) with chloramine-T is described. The products beta-hydroxy-beta-toluenesulfonamides were reduced with sodium in liquid ammonia to give the corresponding beta-amino alcohols with 48-83% yields. The methylation-reduction of beta-hydroxy-beta-toluene-sulfonamides gave beta-methylamino alcohols with 33-55% yields. (C) 2009 Elsevier Ltd. All rights reserved.
