Abstract
- A useful synthesis of 3-methylthio-6-methyl-pyrano[4,3-c]pyrazol-4(2H)-ones via 3-(bis-methylthio)methylene-5,6-dihydro-6-alkyl(aryl)-2H-pyran-2,4-dione with hydrazine as well as methyl and phenyl hydrazines is described and the mechanism of the formation is discussed. © 2003 Wiley Periodicals, Inc.
