The solid phase synthesis of 2,4,5-trisubstituted thiomorpholin-3-ones
is described. Starting from a resin-bound protected cysteine, and emp
loying reductive alkylation and amide formation, thiomorpholin-3-one d
erivatives have been synthesized through intramolecular thioether form
ation in good yield and high purity. (C) 1998 Elsevier Science Ltd. Al
