  Toward Lead-Oriented Synthesis: One-Pot Version of Castagnoli Condensation with Nonactivated Alicyclic Anhydrides

  摘要：

  One-pot variation of Castagnoli condensation, that is, reaction of cyclic anhydrides, amines, and aldehydes, has been developed as a combinatorial approach to 1,2-disubstituted 5-oxopyrrolidine- and 6-oxopiperidine-3-carboxylic acids, as well as their benzo-analogues. Utility of the method to multigram preparation of building blocks and synthetic intermediates was also demonstrated. The final products are obtained in high yields and diastereoselectivity. The method fits well in the concept of lead-oriented synthesis; in particular, it can be used for the design of lead-like Compound libraries, even if the strictest cut-offs are applied to the physicochemical properties of their members.

  Identification of antitumor activity of pyrazole oxime ethers

  摘要：

  A series of pyrazole oxime ether derivatives were prepared and examined as cytotoxic agents. In particular, 5-phenoxypyrazole was comparable to doxorubicin, while exhibiting very potent cytotoxicity against XF 498 and HCT15. (c) 2005 Elsevier Ltd. All rights reserved.

  Abstract The nucleophilic aromatic substitution on 5‐chloropyrazoles activated by the electron‐withdrawing formyl group offers a useful method to introduce a wide range of N‐containing heterocycles into them. The rate of reaction was greatly affected by the electronic nature of the N‐1 substitution.
