Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Catalysis
  • Alkene

Catalysis, Organic chemistry, Enantioselective synthesis, Palladium and Combinatorial chemistry are his primary areas of study. His Catalysis study integrates concerns from other disciplines, such as Medicinal chemistry and Amine gas treating. His Medicinal chemistry study incorporates themes from Reaction conditions and Tetrahydroisoquinoline derivatives.

His study in the field of Yield, Fluorine, Stereoisomerism and Copper is also linked to topics like Trifluoromethylation. His Enantioselective synthesis study combines topics from a wide range of disciplines, such as Bifunctional, Bifunctional catalyst, Lewis acids and bases and Catalyst selectivity. As a part of the same scientific family, he mostly works in the field of Palladium, focusing on Michael reaction and, on occasion, Ionic liquid, Brønsted–Lowry acid–base theory and Enantiomer.

His most cited work include:

  • Catalytic enantioselective fluorination of oxindoles. (255 citations)
  • An efficient enantioselective fluorination of various β-ketoesters catalyzed by chiral palladium complexes (244 citations)
  • A New Bifunctional Asymmetric Catalysis: An Efficient Catalytic Asymmetric Cyanosilylation of Aldehydes (215 citations)

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

His primary areas of study are Catalysis, Organic chemistry, Enantioselective synthesis, Combinatorial chemistry and Palladium. His Catalysis research includes themes of Halogenation and Medicinal chemistry. His work on Yield, Aldol reaction and BINAP as part of general Organic chemistry research is frequently linked to Trifluoromethylation and Aryl, bridging the gap between disciplines.

His studies examine the connections between Yield and genetics, as well as such issues in Regioselectivity, with regards to Desymmetrization. His studies deal with areas such as Bifunctional, Michael reaction, Reaction mechanism, Nucleophile and Amine gas treating as well as Enantioselective synthesis. His Combinatorial chemistry research is multidisciplinary, relying on both Ethanol and Methylene.

He most often published in these fields:

  • Catalysis (65.36%)
  • Organic chemistry (51.96%)
  • Enantioselective synthesis (45.81%)

What were the highlights of his more recent work (between 2016-2021)?

  • Catalysis (65.36%)
  • Enantioselective synthesis (45.81%)
  • Combinatorial chemistry (25.14%)

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

Yoshitaka Hamashima spends much of his time researching Catalysis, Enantioselective synthesis, Combinatorial chemistry, Organic chemistry and Reagent. His Catalysis research is multidisciplinary, incorporating perspectives in Yield and Photochemistry. His study in Enantioselective synthesis is interdisciplinary in nature, drawing from both Alkene, Amide and Monoxide.

The Combinatorial chemistry study combines topics in areas such as Indole test and Synergistic catalysis. His work blends Organic chemistry and Product studies together. The various areas that Yoshitaka Hamashima examines in his Reagent study include Intestinal absorption, Nanoparticle, Aromaticity and Polymer.

Between 2016 and 2021, his most popular works were:

  • Benzylic C–H Trifluoromethylation via Photoenol (27 citations)
  • Regio- and chemoselective Csp3–H arylation of benzylamines by single electron transfer/hydrogen atom transfer synergistic catalysis (23 citations)
  • Photofluorination of Aliphatic C-H Bonds Promoted by the Phthalimide Group. (21 citations)

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

  • Organic chemistry
  • Catalysis
  • Alkene

His primary scientific interests are in Catalysis, Reagent, Medicinal chemistry, Trifluoromethylation and Photochemistry. His biological study spans a wide range of topics, including Yield, Radical ion and Aniline. His research in Yield intersects with topics in Inorganic chemistry, Reaction rate, Allyl alcohol, Triethyl orthoacetate and Reaction step.

His biological study deals with issues like Selectfluor, which deal with fields such as Electrophile, Dicarboxylic acid and Phase-transfer catalyst. The concepts of his Photochemistry study are interwoven with issues in Photoredox catalysis, Nitrogen atom, Cyanation, Redox and Cyanide. Moiety is the topic of his studies on Organic chemistry and Stereochemistry.
