Heterocycles from N-Benzoylthioamides and Dinucleophilic Reagents

Whitfield, Lawrence L.,Papadopoulos, Eleftherios P.

, p. 1197 - 1201 (2007/10/02)

N-Benzoylthioamides (I) react with hydrazines and hydroxylamine to form 1H-1,2,4-triazoles and 1,2,4-oxazoles, respectively.A similar treatment of the S-methyl derivatives of 1 with amidines leads to 1,3,5-triazines.Ethyl N-benzoylthiocarbamate undergoes analogous reactions to yield the corresponding ethoxyheterocycles.
