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.
