intermolecular alkynylation reactions of various alkoxy, acetoxylactams, and hydroxylactams. This chemistry broadens the scope of iron catalysis by highlighting new aspects of iron salts σ-Lewis acidity. More importantly, this approach is amenable to an unprecedented tandem intermolecular alkynylation/intramolecular hydration sequence affording expedient access to a new carbonyl structures.

The pyrrolo[2,1-b]thieno[2,3-e][1,3]thiazocinediones (6a,b) resulting from a few known eight membered ring cyclization were successfully described via the Frieder-Crafts cyclodehydration of the appropriates 1-(thien-2'-ylmethyl)-2-pyrrolidinone-5-thioglycolic acids (5a,b).

A synthesis of oxopyrrolidino[2]azepinones annelated to a thiophene ring 3a,b,c is described starting from succinimide and halogenomethylthiophenes 6a,b,c. Stereoselective reduction, Schmidt reaction and the Beckmann rearrangement of the oximes of the ketones 3a,b,c are studied.
