Hiroki Yoneyama, Kenji Uemura, Yoshihide Usami, Shinya Harusawa
Tetrahedron   74 2143-2150   Apr 2018
© 2018 Elsevier Ltd We recently reported a novel synthetic method for five-membered unsaturated cyclic compounds from ketones involving cyanophosphates (CPs) under neutral conditions, in which alkylidene carbenes generated through tetrazole-fragme...
Hiroki Yoneyama, Fumiko Hikasa, Daiki Fujisue, Yoshihide Usami, Zheng Yun Zhao, Shinya Harusawa
Heterocycles   96 106-126   Jan 2018
© 2018 The Japan Institute of Heterocyclic Chemistry. Novel C4-linked triazol C0-, C1- and C2-ribonucleoside phosphoramidites for RNA catalysis probing were synthesized from β-ribofuranosyl-Cn-acetylenes (n = 0–2), which were efficiently prepared ...
Yoshihide Usami, Aoi Kohno, Hiroki Yoneyama, Shinya Harusawa
Molecules   23    Jan 2018
© 2018 by the authors. Synthesis of novel pyrazole-fused heterocycles, i.e., dihydro-1H- or 2H-oxepino[3,2-c] pyrazoles (6 or 7) from 4-allyloxy-1H-pyrazoles (1) via combination of Claisen rearrangement and ring-closing metathesis (RCM) has been a...
Hiroki Yoneyama, Masahiro Numata, Kenji Uemura, Yoshihide Usami, Shinya Harusawa
Journal of Organic Chemistry   82 5538-5556   Jun 2017
© 2017 American Chemical Society. Cyanophosphates (CPs) can be easily prepared from either ketones or aldehydes, and their reaction with NaN3-Et3N·HCl results in the formation of azidotetrazoles. Under microwave irradiation, successive fragmentati...
