alkyl group and the like; n is an integer of 1 to 3, a prodrug thereof and a pharmaceutically acceptable salt thereof show selective and potent CETP inhibitory activity, and therefore, they can be provided as therapeutic or prophylactic agents for hyperlipidemia or arteriosclerosis and the like.
N,N-Substituted amine derivatives were designed by utilizing a bioisosterism strategy. Consequently, twenty-two compounds were synthesized and evaluated for their inhibitory activity against CETP. Structure-activity relationship (SAR) studies indicate that hydrophilic groups at the 2-position of the tetrazole and 3,5-bistrifluoromethyl groups on the benzene ring provide important contributions to the

the aerobicoxidation of alcohols. Use of a dilute oxygen gas source (8% O2 in N2) ensures that the oxygen/organic mixture never enters the explosive regime, and efficient gas-liquid mixing in the reactor minimizes decomposition of the homogeneous catalyst into inactive Pd metal. These results provide the basis for large-scale implementation of palladium-catalyzed (and other) aerobicoxidation reactions
