Abstract

Compounds of Formula I, including pharmaceutically acceptable salts of the compounds, are CETP inhibitors, and are useful for raising HDL-cholesterol, reducing LDL-cholesterol, and for treating or preventing atherosclerosis. In the compounds of Formula 1, A1 and A2 are each an aromatic ring, a 5-6-membered heterocyclic ring, an aromatic ring fused to a heterocyclic ring, a phenyl ring fused to a heterocyclic ring, or a cycloalkyl ring.

(c) a 5-6-membered heterocyclic ring having 1-4 heteroatoms independently selected from N, S, and O, and optionally also comprising 1-3 double bonds and a carbonyl group or —N(O)— group, wherein the point of attachment of A1 to the attached phenyl ring is a carbon atom;
and
(d) a benzoheterocyclic ring comprising a phenyl ring fused to a 5-6-membered heterocyclic ring having 1-3 heteroatoms independently selected from O, N, and S, and optionally 1-2 double bonds, wherein the point of attachment of A1 to the attached phenyl ring is a carbon atom;
A2 is selected from the group consisting of:
