description K. Barry Sharpless Overview

K. Barry Sharpless is an organic chemist associated with two distinct contributions: asymmetric catalytic oxidation and click chemistry. His oxidation methods help chemists control molecular handedness, producing a preferred spatial form of a compound. Such selectivity matters in medicinal chemistry because mirror-image molecules can behave differently in biological systems.

This work earned him a share of the Nobel Prize in Chemistry. Click chemistry expresses a separate approach to assembling molecules through efficient, selective reactions. Copper-catalyzed coupling of azides and alkynes became a prominent example, but the broader concept is not limited to that reaction or derived from asymmetric oxidation. Sharpless shared another chemistry Nobel for work on click chemistry.

His contributions are relevant to researchers developing reliable synthesis methods, with applications extending into drug discovery and materials science.

help K. Barry Sharpless FAQ

Why did K. Barry Sharpless win the Nobel Prize in Chemistry in 2001?

Sharpless shared the 2001 Nobel Prize for work on chirally catalyzed oxidation reactions. His name is attached to reactions such as the Sharpless epoxidation and Sharpless asymmetric dihydroxylation.

Did K. Barry Sharpless win a second Nobel Prize?

Yes, Sharpless shared the 2022 Nobel Prize in Chemistry for click chemistry and bioorthogonal chemistry. He became one of the rare people to win two Nobel Prizes in the sciences.

What is click chemistry in Sharpless's work?

Click chemistry refers to reliable, modular reactions that join molecular building blocks efficiently. The copper-catalyzed azide-alkyne cycloaddition became one of the best-known examples.

Where has K. Barry Sharpless worked academically?

Sharpless has been strongly associated with the Scripps Research Institute in California. His career also included work at institutions such as MIT and Stanford.
