Iminium ions, generated in aqueous solution from secondary amines and formaldehyde, undergo a Barbier-type allylation mediated by tin, aluminum and zinc. The reaction is catalyzed by copper and produces tertiary homoallylamines in up to 85% yield.

The synthesis of 1-butylpyrrolidine and its derivatives (1-butylpyrrolidine with a little of 1-butenylpyrrolidines) was developed via a one-pot method from ammonia and 1,4-butandiol. Here, the product of 1-butylpyrrolidine was emphatically investigated, and the yield was 76% under the optimized conditions. Such a route was realized through successive N-alkylation using aqueous ammonia as the nitrogen source over the CuNiPd/ZSM-5 catalyst, which was prepared by a simple incipient wetness method. In this route, 1,4-butandiol not only participated in the formation of the N-heterocycle, but also acted as an alkylating reagent. This work offers a straightforward, economical route for 1-butylpyrrolidine and its derivatives. This journal is

The synthesis of (±)-heliotridane and (6S,7S)-dihydroxyheliotridane via sequential hydrogen atom abstraction and cyclisation

Treatment of N-(3-bromo-3-butenyl)pyrrolidine derivatives with tributyltin hydride and AIBN leads to hydrogen atom transfer of the intermediate vinyl radicals to give α-amino radicals which then cyclise stereoselectively yielding pyrrolizidines 1 and 13.
