  Two new improved approaches to the synthesis of coumarin-based prodrugs

  摘要：

  Our laboratory has recently reported the development of a coumarin-based, esterase-sensitive prodrug system for the preparation of prodrugs of amines, peptides, and peptidomimetics. Biological evaluations including animal studies have demonstrated me clinical potential of this prodrug system. However, the original synthetic method used required a long sequence of reactions with a relatively low overall yield. In this report, we describe two new approaches to the synthesis of these coumarin-based prodrugs. The first approach is a photochemical approach taking advantage of the photoisomerization of cinnamic acid and its derivatives. The second approach is through the catalytic hydrogenation of a triple bond for the generation of me cis double bond in the coumarinic acid moiety. Both approaches allow for the synthesis of these prodrugs in fewer steps with much improved overall yield. (C) 1999 Elsevier Science Ltd. All rights reserved.
