摘要
In this paper we described the synthesis of the cis-2-azabicyclo[3.3.0]octane derivative (5b) employing highly diastereoselective mercury(II)-mediated intramolecular amino-cyclization, followed by reductive demercuration of ethyl erythro-1-allyl-2-amino-1-cyclopentancarboxylate (7b). Molecular dynamic studies were performed in order to find a suitable explanation of the diastereoselectivity of azamercuration in comparison with corresponding oxymercuration process.
