Masaji Ohno mainly investigates Stereochemistry, Organic chemistry, Enantioselective synthesis, Asymmetric induction and Medicinal chemistry. His work in Stereochemistry covers topics such as DNA which are related to areas like Mechanism of action. In general Organic chemistry, his work in Alkylation, Acetal, Esterase and Synthon is often linked to Fluoride linking many areas of study.
Enantioselective synthesis is a subfield of Catalysis that Masaji Ohno studies. The various areas that he examines in his Asymmetric induction study include Diethylzinc, Toluene and Combinatorial chemistry. The concepts of his Medicinal chemistry study are interwoven with issues in Chiral ligand and Lewis acids and bases.
His primary scientific interests are in Stereochemistry, Organic chemistry, Enantioselective synthesis, Total synthesis and Hydrolysis. His work in Stereochemistry addresses subjects such as Binding site, which are connected to disciplines such as Transition metal. His study on Catalysis, Synthon, Alkyl and Reagent is often connected to Fluoride as part of broader study in Organic chemistry.
His study in the fields of Chiral ligand under the domain of Enantioselective synthesis overlaps with other disciplines such as Aminocyclitol. His Retrosynthetic analysis study, which is part of a larger body of work in Total synthesis, is frequently linked to Rhizoxin, bridging the gap between disciplines. Masaji Ohno has researched Hydrolysis in several fields, including Esterase and Enzyme.
His primary scientific interests are in Stereochemistry, Organic chemistry, Enantioselective synthesis, Catalysis and Stereoselectivity. He combines subjects such as Glycosylation and Binding site with his study of Stereochemistry. His work on Carboxylic acid and Thioester as part of general Organic chemistry study is frequently connected to Fluoride, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.
His Enantioselective synthesis research is multidisciplinary, incorporating elements of Hydrolysis, Esterase, Aldehyde and Synthon. His Catalysis research integrates issues from Combinatorial chemistry, Reagent and Gallium. His Moiety study incorporates themes from Yield, Metal Binding Site, DNA, Enzyme and Fortimicin A.
Organic chemistry, Enantioselective synthesis, Stereochemistry, Catalysis and Aldehyde are his primary areas of study. His Enantioselective synthesis research includes elements of Medicinal chemistry, Lewis acids and bases and Synthon. His work carried out in the field of Synthon brings together such families of science as Hydrolysis and Esterase.
The Stereochemistry study combines topics in areas such as DNA and Stereoselectivity. His biological study spans a wide range of topics, including Reagent and Glycoside. The Aldehyde study which covers Aliphatic compound that intersects with Hexanal and Zinc.
