Diastereoselective cyclisation of N-alkenylideneamines into 3,4-dihydro–2H-pyrrol-1-ium halides
A number of new chiral 2-(alpha-bromoalkyl)pyrrolinium salts and 2-(alpha-selenoalkyl)pyrrolidines were synthesized by the halocyclisation and selenocyclisation, respectively, of N-(alkenylidene)alkylamines and subsequent reduction. These cyclisations were implemented in a diastereomeric fashion for the first time. Substrate control (starting imines possessing chirality in the N-alkyl or the N-alkenyl substituent) and reagent control (chiral organoselenenyl bromides) were applied. Asymmetric induction by stereocentres of the alkenylidene or double asymmetric induction by chiral selenenyl bromides on unsaturated imines with a chiral N-alkyl group resulted in diatereoselectivities up to 84:16.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 1119-34-2, you can contact me at any time and look forward to more communication. SDS of cas: 1119-34-2.
