a mixture of ethanol and water yields the expected lactams, we exemplified the reaction and procedure with the preparation of a library of 80 members. Our synthesis scheme is validated for synthesis scales from 1 to 100 mg. Therefore, it can be used both to produce rapidly test samples for HTS as well as to prepare intermediates for the synthesis of more elaborated nature-inspired compounds.

[equation--see text] The first enantioselective synthesis of the martinelline core (-)-3 is reported. The synthesis of (-)-3 from N-allyl-N-(benzyloxycarbonyl)-2-iodoaniline (12) proceeded in seven steps and 23% overall yield. In addition, the preparation of a carbocyclic model system is described.
