Synthesis of lithium 1-alkynesulfenates by the mild oxidation of thiolates with a pinacolone-derived N-sulfonyloxaziridine
Lithium 1-alkynethiolates, generated by a base-induced ring cleavage of 4-substituted 1,2,3-thiadiazoles, were efficiently converted into the corresponding sulfenate salts by mild oxidation using an N-sulfonyloxaziridine derived from pinacolone. In situ S

ON THE REGIOSELECTIVITY IN THE HURD-MORI REACTION
Various α-substituted (Y) acetone hydrazones were subjected to the Hurd-Mori reaction to give the 4-methyl-5-Y-substituted 1,2,3-thiadiazoles and/or 4-Y-CH2 derivatives.The ratio of the two products changed drastically depending on the kind of the substit
