N. Dekimpe et al., SYNTHESIS OF 2-IMINO-4-THIAZOLINES, 2-IMINO-4-ALKOXYTHIAZOLIDINES, THIAZOLES AND 4-IMIDAZOLIN-2-ONES FROM ALPHA-HALOMETHYL KETIMINES, Journal of heterocyclic chemistry, 33(4), 1996, pp. 1179-1183
A variety of heterocycles, including 3,4-disubstituted-2-imino-4-thiaz
olines, 3,4-disubstituted-4-methoxy-2-iminothiazolidines, 2,4-disubsti
tuted-thiazoles, 2-amino-4-substituted-thiazoles and 1,5-disubstituted
-4-imidazolin-2-ones, were synthesized from alpha-chloromethyl and alp
ha-bromomethyl ketimines by condensation with potassium thiocyanate, t
hiourea, ammonium thiocyanate and potassium cyanate.
