A facile synthesis of antitumoral indeno[1,2-c]pyrazole-4-one by mild oxidation with molecular oxygen
摘要:
An efficient, convenient, and general synthetic method for indeno[1,2-c]pyrazole-4-ones through oxidation of indeno-pyrazoles by treatment with a base and molecular oxygen is described, and a possible mechanism for the oxidation is proposed. The product indeno[1,2-c]pyrazole-4-ones were elaborated further by Suzuki coupling and Mitsunobu reaction. (c) 2005 Elsevier Ltd. All rights reserved.
This invention relates to certain 3-aryl or 3-heteroaryl pyrazoles with 4,5(3,4)-bicyclic ring fusion which are inhibitors of protein kinase activity, of which some are novel compounds, to pharmaceutical compositions containing these pyrazoles and to processes for preparing these pyrazoles.
