Abstract:A Novel Synthesis of trans-Enynes from Substituted Tetrahydropyrans. -Cleavage of 3-bromo-2-ethynyltetrahydropyrans such as (I) and (V) with BuLi or in situ generated cobaloxime(I) results in a novel method for the synthesis of trans-enynes [cf. (III) and (VI)]. -(KARADOGAN, BURHAN; EDWARDS, NEIL; PARSONS, PHILIP J.; Tetrahedron Lett. 40 (1999) 32, 5931-5934; Chem. Lab., Sch. Chem., Phys. Environ. Sci., Univ.
