  The Synthesis of N-{2-Amino-4-substituted [(Pyrrolo[2,3-d]pyrimidin-5-yl)ethyl]benzoyl}-L-glutamic Acids as Antineoplastic Agents

  摘要：

  A series of N-{2-amino-4-substituted[(pyrrolo[2,3-d]pyrimidin-5-yl)ethyl]benzoyl}-L-glutamic acids were synthesized. In this current synthesis, compound 2-amino-4-chloro-pyrrolo[2,3-d]pyrimidine (4) was selected as an important precursor for the preparation of key intermediates such as 5b, 10b, 15a and 15b. These highly functionalized pyrrolo[2,3-d]pyrimidines were then later coupled with either 4-ethynylbenzoylglutamate or 4-iodobenzoylglutamate in a palladium catalyzed Heck reaction and thus provided the basic skeleton of the targeted molecules. The availability of the chlorine atom at the 4-position of the pyrrolopyrimidine nucleus has allowed us to introduce different substituents at this position efficiently. By this approach, we were able to prepare a variety of 4-substituted pyrrolo[2,3d]pyrimidine based folate antagonists (2a-2g) which are closely related to the novel thymidylate synthase inhibitor LY231514. In vitro analysis has demonstrated that some of these agents are highly cytotoxic against human leukemic cells (CCRF-CEM) in culture.
