Takashi Ohshima spends much of his time researching Catalysis, Organic chemistry, Enantioselective synthesis, Total synthesis and Michael reaction. His study in Catalysis is interdisciplinary in nature, drawing from both Combinatorial chemistry, Indium, Ligand and Medicinal chemistry. Takashi Ohshima has researched Indium in several fields, including Bifunctional and Substrate.
In his study, Phase-transfer catalyst, Mannich reaction, Glycine and Amino acid is strongly linked to Polymer chemistry, which falls under the umbrella field of Enantioselective synthesis. In general Total synthesis study, his work on Eleutherobin often relates to the realm of Biological profile, thereby connecting several areas of interest. He has included themes like Alkylation, Lewis acids and bases and Reactivity in his Michael reaction study.
Takashi Ohshima mostly deals with Catalysis, Organic chemistry, Combinatorial chemistry, Enantioselective synthesis and Medicinal chemistry. His Catalysis research is multidisciplinary, incorporating elements of Yield and Reactivity. His study in Organic chemistry concentrates on Total synthesis, Zinc, Chemoselectivity, Alkynylation and Amination.
His work deals with themes such as Epoxide, Stereochemistry and Carboxylic acid, which intersect with Enantioselective synthesis. His research integrates issues of Molecule and Stereoselectivity in his study of Stereochemistry. His Medicinal chemistry research incorporates elements of Substrate, Alkyl and Reaction mechanism.
His main research concerns Catalysis, Organic chemistry, Combinatorial chemistry, Transesterification and Enantioselective synthesis. His work carried out in the field of Catalysis brings together such families of science as Amino acid, Yield, Carboxylic acid, Ligand and Reactivity.
