Regioselective preparation of saturated spirocyclic and ring-expanded fused pyrazoles
Merchant, Rohan R.,Allwood, Daniel M.,Blakemore, David C.,Ley, Steven V.
, p. 8800 - 8811 (2014)
Saturated bicyclic pyrazoles represent an important class of biologically active molecules, but their preparation can be hampered by labor-intensive synthesis of required starting materials. A convenient one- or two-step procedure for the synthesis of sat

Described herein are the palladium-catalyzed cross-coupling reactions of cyclobutanone-derived N-sulfonylhydrazones with aryl or benzyl halides, suggesting that the metal carbene process and β-hydride elimination can smoothly occur in strained ring system

Treatment of acetylhydrazones 2, ethoxycarbonylhydrazones 3, p-tolylsulfonylhydrazones 4 or semicarbazones 5 with thionyl chloride leads to the 1,2,3-thiadiazoles 6a-o.Sulfuryl chloride on the other hand accomplishes the transfer of chlorine without incorporating a sulfur atom.The new synthesized 1,2,3-thiadiazoles 6g-o are characterized in detail by spectroscopic methods.
