Asymmetric synthesis of tetrahydrobenzodiazepines was achieved by transfer hydrogenation of dihydrobenzodiazepines with benzothiazoline having a hydrogenbonding donor substituent by means of a newly synthesized chiral phosphoric acid. This method ...
Takahiko Akiyama was born in Kurashiki (Japan) in 1958 and did his undergraduate and graduate studies at The University of Tokyo. After working at Shionogi Research Laboratories, Shionogi & Co., Ltd., as a research chemist, he was appointed as an ...
A strategy for oxidative kinetic resolution of racemic indolines was developed, employing salicylaldehyde derivative as the pre-resolving reagent and chiral phosphoric acid as the catalyst. The iminium intermediate, formed by the condensation reac...
The titanium tetrachloride-catalyzed hydrodefluorination reaction of trifluorotoluene derivatives was developed using triethylsilane as the reducing agent. The reaction produced various toluene derivatives with high chemoselectivities by means of ...
