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.

scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
