Palladium (O) catalyzed tandem alkylation and SN′ cyclization of 1,4-dichlorobut-2-ene by the N-(diphenylmethylene)acetonitrile. A stereoselective synthesis of 1-aminocyclopropanecarboxylic acids
Racemic coronamic acid has been prepared with 100% diastereoselectivity from one pot palladium (0) catalyzed alkylation and S-N cyclization of 1,4-dichlorobut-2-ene by the benzophenone Schiff base of aminoacetonitrile.
