Enantioenriched α-Vinyl 1,4-Benzodiazepines and 1,4-Benzoxazepines via Enantioselective Rhodium-Catalyzed Hydrofunctionalizations of Alkynes and Allenes
Benzofused seven-membered heterocycles such as 1,4-benzo[e]diazepines (1,4-BZDs) and 1,4-benzo[e]oxazepines (1,4-BZOs) were efficiently synthesized by Rh-catalyzed hydrofunctionalization of internal alkynes and allenes in good to excellent yields. The asy

Diastereoselective intramolecular pinacol couplings of sulfinyl iron(0) diene complexes
3-(2-Fonnylaryl)-1-sulfinyl-(1Z, 3E)-pentadien-5-al iron tricarbonyl complexes were prepared to examine the feasibility and diastereoselectivity of intramolecular pinacol couplings on such substrates. It was found that the pinacol coupling, promoted by VC
