Efficient enantioselective synthesis of 2-substituted thiomorpholin-3-ones
摘要:
The synthesis of enantiomerically pure 4-(2-hydroxy-(1R)-phenylethyl)-thiomorpholin-3-one 2 from (R)-phenylglycine methyl ester, S-benzylthioglycolic acid and bromoacetic acid is reported. Stereoselective C-2 alkylation of 2, performed using various electrophiles, leads to enantiomerically pure 2-substituted thiomorpholin-3-ones after N-deprotection. (C) 2003 Elsevier Ltd.
