Asymmetric synthesis of 1,4-cycloheptadienes and bicyclo[3.2.1]octa-2,6-dienes by rhodium(II) N-(p-(tert-butyl)phenylsulfonyl)prolinate catalyzed reactions between vinyldiazomethanes and dienes

Rhodium(II) (S)-(N-p(tertbutyl)phenylsulfonyl)prolinate catalyzed decomposition of vinyldiazomethanes in the presence of dienes results in a tandem cyclopropanation/Cope rearrangement, leading to a general and enantioselective approach for the construction of seven-membered carbocycles.
