Abstrakt: The addition of dimethyl ethynyl carbinol to the carbonyl group of 2, 5-dimethyl-4-piperidinone under the conditions of the Favorskii reaction has been studied. It has been shown that the addition takes place stereo-selectively and leads to the formation of a single isomeric acetylenic glycol. The hydration of this glycol has given a heterocyclic tetrahydrofuran with a spiran structure. The exhaustive hydrogenation of the acetylenic glycol has yielded the corresponding saturated glycol. By its cyclization a tetrahydrofuran derivative has been synthesized.
