Cw. Chan et al., AN EFFICIENT SYNTHESIS OF 1,2,4-OXATHIAZOLES FROM N-ACYLTHIOUREA DERIVATIVES, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(3), 1997, pp. 216-219
1,2,4-Oxathiazoles have been synthesized from their precursors, the N-
acylthioureas by oxidative cyclization reaction. Ring structure and ti
le charge distribution above the ring have also been studied.
