General description
Benzyl 4-(trifluoromethylsulfonyloxy)-3-(trimethylsilyl)-5,6-dihydropyridine-1(2H)-carboxylate is a silyl triflate. It can be prepared from 4-methoxypyridine, via a three-step route.
Application
Benzyl 4-(trifluoromethylsulfonyloxy)-3-(trimethylsilyl)-5,6-dihydropyridine-1(2H)-carboxylate may be used as a starting reagent for the synthesis of 3,4-piperidyne. 3,4-Piperidyne is a precursor for the synthesis of various functionalized heterocyclic compounds.
Building block is a precursor for a highly useful azacyclohexyne intermediate, which is generated in the presence of Cesium Fluoride. The azacyclohexyne can be trapped in situ with dipolariphiles and other dienes to form bicyclic carbocycles and heterocycles.

The Garg group develops methods for the synthesis of natural products and pharmaceuticals. One key method pertains to heterocyclic arynes, such as indolynes and pyridynes, which are generated in situ from silyltriflate precursors under mild fluoride based reaction conditions.

We report the generation of the first 3,4-piperidyne and its use as a building block for the synthesis of annulated piperidines. Experimental and computational studies of this intermediate are disclosed, along with comparisons to the well-known 3,4-pyridyne. The distortion/interaction model
