Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Catalysis
  • Alkene

Takeshi Ohkuma mostly deals with Organic chemistry, Asymmetric hydrogenation, Catalysis, Enantioselective synthesis and Noyori asymmetric hydrogenation. Many of his research projects under Organic chemistry are closely connected to Homogeneous with Homogeneous, tying the diverse disciplines of science together. As a part of the same scientific study, Takeshi Ohkuma usually deals with the Asymmetric hydrogenation, concentrating on Medicinal chemistry and frequently concerns with Acetophenone.

His study in BINAP and Ruthenium falls within the category of Catalysis. His Ruthenium study combines topics from a wide range of disciplines, such as Stereochemistry and Reaction mechanism. His Noyori asymmetric hydrogenation study incorporates themes from Ketone and Transfer hydrogenation.

His most cited work include:

  • Asymmetric Catalysis by Architectural and Functional Molecular Engineering: Practical Chemo‐ and Stereoselective Hydrogenation of Ketones (1332 citations)
  • Asymmetric hydrogenation of .beta.-keto carboxylic esters. A practical, purely chemical access to .beta.-hydroxy esters in high enantiomeric purity (534 citations)
  • PRACTICAL ENANTIOSELECTIVE HYDROGENATION OF AROMATIC KETONES (497 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of investigation include Catalysis, Organic chemistry, Asymmetric hydrogenation, Medicinal chemistry and Enantioselective synthesis. His research investigates the connection with Catalysis and areas like Polymer chemistry which intersect with concerns in Palladium and Alkyne. His work on Noyori asymmetric hydrogenation, Enantiomer, Stereoselectivity and Kinetic resolution as part of general Organic chemistry study is frequently connected to Homogeneous, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.

The Asymmetric hydrogenation study combines topics in areas such as Aromatic ketones, Turnover number, Diamine, Acetophenone and Phosphine. His research integrates issues of Cycloaddition, Trimethylsilyl cyanide, Alkyl and Reaction mechanism in his study of Medicinal chemistry. The concepts of his Enantioselective synthesis study are interwoven with issues in Bifunctional, Aliphatic compound, Ligand, Allylic rearrangement and Stereochemistry.

He most often published in these fields:

  • Catalysis (64.76%)
  • Organic chemistry (53.33%)
  • Asymmetric hydrogenation (41.43%)

What were the highlights of his more recent work (between 2013-2021)?

  • Catalysis (64.76%)
  • Medicinal chemistry (34.29%)
  • Organic chemistry (53.33%)

In recent papers he was focusing on the following fields of study:

Takeshi Ohkuma mainly investigates Catalysis, Medicinal chemistry, Organic chemistry, Ruthenium and Enantioselective synthesis. The various areas that Takeshi Ohkuma examines in his Catalysis study include Nitrile and Polymer chemistry. His work on Palladium nanoparticles and Molecule is typically connected to Homogeneous as part of general Organic chemistry study, connecting several disciplines of science.

His Ruthenium research includes elements of Alcohol and Combinatorial chemistry. In the field of Enantioselective synthesis, his study on Noyori asymmetric hydrogenation overlaps with subjects such as Cover. His Asymmetric hydrogenation study frequently draws parallels with other fields, such as Diamine.

Between 2013 and 2021, his most popular works were:

  • Catalytic Asymmetric Cyanation Reactions (86 citations)
  • Asymmetric conjugate hydrocyanation of α,β-unsaturated N-acylpyrroles with the Ru(phgly)2(binap)-CH3OLi catalyst system. (18 citations)
  • Hydrogenation of nitroarenes with palladium nanoparticles stabilized by alkyne derivatives in homogeneous phase (15 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Catalysis
  • Alkene

Takeshi Ohkuma mainly investigates Catalysis, Medicinal chemistry, Stereoselectivity, Ruthenium and Enantioselective synthesis. He combines subjects such as Nanoparticle and Phase with his study of Catalysis. The study incorporates disciplines such as Chromium, Reactivity and Cycloaddition in addition to Medicinal chemistry.

His Stereoselectivity study results in a more complete grasp of Organic chemistry. He works mostly in the field of Ruthenium, limiting it down to concerns involving Combinatorial chemistry and, occasionally, Lithium. He studies Enantioselective synthesis, focusing on Asymmetric hydrogenation in particular.
