Thiourea-based gemfibrozil analogues as HDL-elevating agents
摘要:
A series of gemfibrozil analogues with a thiourea moiety embedded in the side chain was prepared and evaluated as HDL-elevating agents. Derivatives 8b, 9b, 9c, and 9d were found to be approximately as effective as gemfibrozil (1) for HDL cholesterol elevation. (C) 2002 Elsevier Science Ltd. All rights reserved.

The introduction of a primary aminomethyl unit at the α-position of esters can be achieved in high yield by the silyltrifluoromethanesulphonate-catalysedreaction of ketenesilylacetals (2) with N,N-bis(trimethylsilyl)methoxymethylamine (1).
