The present invention relates to compounds of the formula (I) wherein A1 to A3 and R1 to R9 are defined in the description, and to pharmaceutically acceptable salts thereof, their manufacture, pharmaceutical compositions containing them and their use as medicaments for the treatment and/or prophylaxis of diseases which can be treated with HDL-cholesterol raising agents, such as particularly dyslipidemia, atherosclerosis and cardiovascular diseases.

Conformationally restrained dipeptidyl lactams are building blocks for the synthesis of peptidomimetics, including Freidinger lactams (Figure 1). Few synthetic methodologies toward such moieties allow for incorporation of a stereodefined substituent on the ring nitrogen (i.e., corresponding to an amino acid side chain). Enantiopure Freidinger lactams were obtained by (1) condensation of (S)-tert-butoxycarbonyl
Pyridine, pyridazine, pyrimidine or pyrazine carboxamides as HDL-cholesterol raising agents

A route to enantiomerically pure N-tert-butoxycarbonyl-2-aminocycloalkanones (ring size: 5-8 membered) from the corresponding cycloalkene oxides is described. The procedure involves (1) aminolysis with (S)-alpha-methylbenzylamine/Me3Al and chromatographic separation of diastereomers, (2) hydrogenolysis to afford the trans-2-aminocycloalkanols, (3) tert-butoxycarbonyl (Boc) protection, and (4) PCC oxidation.
