Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Enzyme
  • DNA

Nelson J. Leonard mainly focuses on Stereochemistry, Organic chemistry, Biochemistry, Photochemistry and Cofactor. His work carried out in the field of Stereochemistry brings together such families of science as Phosphate, Adenine nucleotide and Purine. In the subject of general Organic chemistry, his work in Mercuric acetate, Oxidative cyclization and Periodate is often linked to Chemistry and Scope, thereby combining diverse domains of study.

His work in the fields of Biochemistry, such as Enzyme, intersects with other areas such as Corynebacterium. His Photochemistry research incorporates elements of Sulfoxide, Molecule, Fluorescence and Chloroacetaldehyde. While the research belongs to areas of Cofactor, Nelson J. Leonard spends his time largely on the problem of Base pair, intersecting his research to questions surrounding Intramolecular force, Ultraviolet irradiation and Thymine.

His most cited work include:

  • Fluorescent modification of adenosine-containing coenzymes. Biological activities and spectroscopic properties (453 citations)
  • Synthetic spectroscopic models related to coenzymes and base pairs. V. Emission properties of NADH. Studies of fluorescence lifetimes and quantum efficiencies of NADH, AcPyADH, [reduced acetylpyridineadenine dinucleotide] and simplified synthetic models (329 citations)
  • Periodate Oxidation of Sulfides to Sulfoxides. Scope of the Reaction (243 citations)

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

His primary areas of study are Stereochemistry, Organic chemistry, Medicinal chemistry, Biochemistry and Fluorescence. In his research on the topic of Stereochemistry, Biological activity is strongly related with Purine. Nelson J. Leonard studies Bicyclic molecule which is a part of Organic chemistry.

His primary area of study in Medicinal chemistry is in the field of Clemmensen reduction. His study in Enzyme and Adenosine is carried out as part of his Biochemistry studies. Nelson J. Leonard regularly links together related areas like Photochemistry in his Fluorescence studies.

He most often published in these fields:

  • Stereochemistry (37.58%)
  • Organic chemistry (22.46%)
  • Medicinal chemistry (12.74%)

What were the highlights of his more recent work (between 1979-2016)?

  • Stereochemistry (37.58%)
  • Organic chemistry (22.46%)
  • Fluorescence (9.72%)

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

His primary scientific interests are in Stereochemistry, Organic chemistry, Fluorescence, Biochemistry and Bicyclic molecule. Nelson J. Leonard is studying Nuclear magnetic resonance spectroscopy, which is a component of Stereochemistry. The various areas that Nelson J. Leonard examines in his Organic chemistry study include Polymer chemistry and Nucleoside.

His Fluorescence research is multidisciplinary, incorporating elements of Tricyclic, Photoaffinity labeling, Photochemistry, Molecule and Combinatorial chemistry. His Biochemistry study typically links adjacent topics like Fluorescence spectrometry. His Bicyclic molecule research includes elements of Lactam, Alkylation, Catalysis and Methanol.

Between 1979 and 2016, his most popular works were:

  • Etheno-Substituted Nucleotides and Coenzymes: Fluorescence and Biological Activity (132 citations)
  • Studies of tautomers and protonation of adenine and its derivatives by nitrogen-15 nuclear magnetic resonance spectroscopy (78 citations)
  • Synthesis and structure of tri-s-triazine (68 citations)

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

  • Enzyme
  • Organic chemistry
  • DNA

The scientist’s investigation covers issues in Stereochemistry, Organic chemistry, Bicyclic molecule, Biochemistry and Fluorescence. His Stereochemistry research integrates issues from Covalent bond, Base pair, Ribonucleoside and Enzyme. His Organic chemistry study combines topics in areas such as Chemical solution, Polymer chemistry and Medicinal chemistry.

His research in Bicyclic molecule intersects with topics in Enol ether, Catalysis, Methanol and Nitrogen. Nelson J. Leonard studied Biochemistry and Adenine nucleotide that intersect with Adenosine, Binding site, Fluorescence spectrometry, Kinase and c-Raf. In his work, Adduct, Physical chemistry and Computational chemistry is strongly intertwined with Molecule, which is a subfield of Fluorescence.
