Niobium-Catalyzed Intramolecular Addition of O-H and N-H Bonds to Alkenes: A Tool for Hydrofunctionalization

A convenient, versatile, and easy to handle intramolecular hydrofunctionalization of alkenes (C-O and C-N bonds formation) is reported using a novel niobium-based catalytic system. This atom economic and eco-friendly methodology provides an additional synthetic tool for the straightforward formation of valuable building blocks enabling molecular complexity. Various pyran, furan, pyrrolidine, piperidine, lactone, and lactam derivatives as well as spirocyclic compounds are produced in high yields and selectivities.

Unusual iodine catalyzed lactonization of γ-methyl-γ,δ-pentenoic acids: A facile synthesis of γ,γ-dimethyl-γ-butyrolactones

γ,γ-Dimethyl-γ-butyrolactones were exclusively obtained from γ-methyl-γ,δ-pentenoic acids with a catalytic amount of iodine in good yields in methylene chloride.

Cationic iron-catalyzed addition of carboxylic acids to olefins

Cationic iron salts were found to be good catalysts for intraand intermolecular addition of carboxylic acids to olefins, which afforded the corresponding esters in good yields. Copyright
