Rhodium-Catalyzed Intramolecular Cyclopropanation of α-Diazo β-Keto Nitriles Containing an Unsaturated Substituted Cycloalkyl Group
Zhu, Jia-Liang,Wu, Yung-Peng
, p. 1467 - 1472 (2017)
Several α-diazo β-keto nitriles bearing trans -2-allyl-, -vinyl-, or -phenylcycloalkyl groups were prepared and their intramolecular cyclopropanation reactions were examined. In the presence of Rh 2 (OAc) 4 (1 mol%) as a catalyst, th
