A practical, efficientsynthesis of (−)-(2R,4S)-4-[(3,5-bis-trifluoromethyl-benzyl)methoxycarbonylamino]-2-ethyl-6-trifluoromethyl-3,4-dihydro-2H-quinoline-1-carboxylic acidethylester (1), a cholesteryl ester transfer protein (CETP) inhibitor, is described. The key reaction in the synthesis, addition of an N-vinylcarbamate to an iminium ion rapidly followed by an iminium ion cyclization onto the
Cholesteryl ester transfer protein inhibitors, pharmaceutical compositions containing such inhibitors and the use of such inhibitors to elevate certain plasma lipid levels, including high density lipoprotein-cholesterol and to lower certain other plasma lipid levels, such as LDL-cholesterol and triglycerides and accordingly to treat diseases which are exacerbated by low levels of HDL cholesterol and/or high levels of LDL-cholesterol and triglycerides, such as atherosclerosis and cardiovascular diseases in some mammals, including humans.
