Sulfinyl moiety as an internal nucleophile. Part 6: Stereospecific synthesis of 3-amino-2-hydroxy-4-phenylbutanoate
摘要:
A novel and stercospecific synthesis of (2R,3S)-3-amino-2-hydroxy-4-phenylbutanoate (AHPBA) is disclosed. The key step includes regio- and stereospecific functionalization of an alkene by the pendant sulfinyl group. (C) 2003 Elsevier Science Ltd. All rights reserved.

Chiral allylic β-hydroxysulfoxides have been hydroxylated by the osmiumtetroxidecatalyzed reaction. The reaction can be highly stereoselective depending on the nature of the substituant linked to the double bond and the configurations of the sulfoxide and hydroxylic groups. The diastereoselectivity can be as high as 90%.
