Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Catalysis
  • Aldehyde

Yujiro Hayashi mainly investigates Organic chemistry, Enantioselective synthesis, Catalysis, Organocatalysis and Aldol reaction. His work carried out in the field of Enantioselective synthesis brings together such families of science as Reagent, Stereochemistry and Michael reaction. His research in Michael reaction intersects with topics in Diphenylprolinol, Intramolecular force and Nonene.

In general Catalysis, his work in Aldehyde, Mannich reaction and Silyl ether is often linked to Acetaldehyde linking many areas of study. He combines subjects such as Total synthesis and Enamine with his study of Organocatalysis. His Aldol reaction research is multidisciplinary, incorporating elements of Hajos–Parrish–Eder–Sauer–Wiechert reaction, Molecule and Green chemistry.

His most cited work include:

  • Diphenylprolinol Silyl Ethers as Efficient Organocatalysts for the Asymmetric Michael Reaction of Aldehydes and Nitroalkenes (914 citations)
  • Highly diastereo- and enantioselective direct aldol reactions in water. (385 citations)
  • Pot economy and one-pot synthesis (370 citations)

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

His scientific interests lie mostly in Organic chemistry, Catalysis, Enantioselective synthesis, Organocatalysis and Stereochemistry. Aldol reaction, Aldehyde, Michael reaction, Cycloaddition and Yield are among the areas of Organic chemistry where Yujiro Hayashi concentrates his study. His study in Catalysis is interdisciplinary in nature, drawing from both Proline and Medicinal chemistry, Ene reaction.

His studies deal with areas such as Combinatorial chemistry, Intramolecular force, Enamine and Reaction mechanism as well as Enantioselective synthesis. His Organocatalysis study combines topics from a wide range of disciplines, such as Iminium, Nitromethane, Silyl ether and One pot reaction. His Stereochemistry research integrates issues from Stereoselectivity, Ring and Epoxide.

He most often published in these fields:

  • Organic chemistry (58.50%)
  • Catalysis (36.41%)
  • Enantioselective synthesis (31.55%)

What were the highlights of his more recent work (between 2015-2021)?

  • Organic chemistry (58.50%)
  • Catalysis (36.41%)
  • Enantioselective synthesis (31.55%)

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

Yujiro Hayashi focuses on Organic chemistry, Catalysis, Enantioselective synthesis, Michael reaction and Total synthesis. His Catalysis research is multidisciplinary, relying on both Yield, Redox and Molecule. His specific area of interest is Enantioselective synthesis, where Yujiro Hayashi studies Organocatalysis.

The Organocatalysis study combines topics in areas such as Aromatization, Axial symmetry, Chirality and One pot reaction. The study incorporates disciplines such as Diphenylprolinol silyl ether, Medicinal chemistry, Lactone, Nitromethane and Amine gas treating in addition to Michael reaction. His Total synthesis research incorporates elements of Ether, Epimer, Cascade reaction and Atom economy.

Between 2015 and 2021, his most popular works were:

  • Pot economy and one-pot synthesis (370 citations)
  • Time Economical Total Synthesis of (−)-Oseltamivir (39 citations)
  • Sterically Demanding Oxidative Amidation of α-Substituted Malononitriles with Amines Using O2. (25 citations)

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

  • Organic chemistry
  • Catalysis
  • Aldehyde

The scientist’s investigation covers issues in Organic chemistry, Total synthesis, Catalysis, Enantioselective synthesis and Michael reaction. His Organic chemistry study focuses mostly on Amine gas treating, Molecular oxygen and Electrophile. His research in Total synthesis tackles topics such as Epimer which are related to areas like Chirality and Sharpless epoxidation.

Yujiro Hayashi interconnects Nitromethane and Molecule in the investigation of issues within Catalysis. His biological study focuses on Organocatalysis. Yujiro Hayashi studied Michael reaction and Yield that intersect with Thiourea, Chemical reactor, Selectivity, Reagent and Medicinal chemistry.
