PREPARATION OF ß-LACTAMS AND INTERMEDIATES THEREOF |
| abstract |
A synthesis of trans- beta -lactams with an easily convertible group on the C-4 carbon atom of the azetidinone ring comprising a condensation reaction of a metal enolate with an imine with a heterocyclic group or a diimine is provided. Furthermore, new chiral beta -lactams and an enantioselective synthesis of beta -lactams using a chiral imine or alpha -diimine are provided. Also new chiral substituted amino propionic ester metal compounds and new chiral amino acid compounds and processes for the preparation thereof are provided.n[EP0404267A1] |
