A. Zask et al., SYNTHESIS OF 3-MERCAPTO-2(5H)-FURANONES VIA REACTION OF DILITHIO-2,4-THIAZOLIDINEDIONE WITH ALPHA-HALO KETONES, Tetrahedron letters, 34(17), 1993, pp. 2719-2722
A novel synthesis of 3-mercapto-2(5H)-furanones is reported based upon
the reaction of dilithio-2,4-thiazolidinedione with alpha-halo ketone
s. Substitution at the furanone 4- and 5-positions may be controlled b
y the choice of alpha-halo ketone.
