A Concise [3 + 3] Heteroaromatization Synthetic Strategy Afford Dicarboxamide Functionalized Novel Pyrazolo[1,5-a]Pyrimidines
Autor: Yogesh T. Naliapara, Naval Kapuriya, Anilkumar S. Patel
Publikováno v: Journal of Heterocyclic Chemistry. 54:2635-2643
A concise and effective approach to dicarboxamide functionalized novel pyrazolo[1,5-a]pyrimidine has been developed. The method involves [3 + 3] hetroaromatization of oxoketene dithioacetals (16a–x) with 5-amino-N-cyclohexyl-3-(methylthio)-1H-pyraz

Novel oxidative nitrogen to carbon rearrangement found in the conversion of anilines to benzaldoximes by treating with HCHO/H2O2
Autor: Rajesh Kakadiya, Ching-Huang Chen, Chao-Ting Wu, Narsinh M. Dodia, Yi-Wen Lin, Tsann-Long Su, Naval Kapuriya, Kalpana Kapuriya, Yogesh T. Naliapara
Publikováno v: Tetrahedron Letters. 49:2886-2890
Novel rearrangement was found by reacting anilines with HCHO/H2O2 resulting in the synthesis of various benzaldoximes. The mechanism of the rearrangement is proposed and suggested that the rearrangement might proceed via unstable N-phenyloxazirane in
