An expeditious and convenient method for the generation of 11-21-membered intramolecular macrocyclic sulfonium ylides using catalytic Rh2(OAc)4 is presented. Using this approach, a wide variety of sulfur-macrocycles incorporating the
Cyclization of 2-(2-bromoethoxy)-acetophenones and 5-(ω-haloalkoxy)- 1,5-dihydro-2H-pyrrol-2-ones - Formation of five- to eight-membered oxygen-containing heterocycles via intramolecular alkylation

Under basic conditions (lithium diisopropylamide or sodium hydride in THF) 2-(2-bromoethoxy)-acetophenones were transformed to 3,4-dihydro[1]benzoxepin- 5(2H)-ones (homochromanones) in high yields. The preparation of novel tetrahydropyrano[2,3-b]pyrrol-6(
