Synthesis of new 2-amino-4H-thiopyran derivatives via the one-pot reaction between 3,4-dihydro-3-((benzylamino)methylene)-4-thioxochromen-2-ones and alkyl-2-cyanoacetates in the presence of nano-ZnO catalysis

Facile one-pot synthesis of hydroxylated 1,3-dithiane-pyrazolone hybrids

“…In the past decade, the reactions of epichlorohydrin (ECH), carbon disul de, and CH-acids (compounds 1, Scheme 1) have been of interest to organic chemists for synthesizing oxathiolane derivatives 2 [20][21][22]. Building on our research in sulfur-containing heterocyclic chemistry [23][24][25] and hybrid compound synthesis [26-29], we aimed to synthesize new pyrazolone and oxathiolane hybrids using the reaction of pyrazolone and carbon disul de with ECH.…”
