B. Simonot et G. Rousseau, GEM-DIMETHYL EFFECT IN THE FORMATION OF 7 TO 11-MEMBERED RING LACTONES BY IODOLACTONIZATION, Tetrahedron letters, 34(28), 1993, pp. 4527-4530
The influence of a gem-dimethyl group on an iodine-induced cyclisation
of omega-alkenoic acids, leading to seven-membered and medium ring la
ctones was studied.
