THE

SARPONG

GROUP

 

exploring organic chemistry through

total synthesis and methods development

 

Our ResearchOur Values

Research Interests

Natural Products

Natural products provide a platform for developing solutions to longstanding problems in chemical synthesis. Our group does this through the development of novel strategies toward challenging targets.

Methods Development

Development of new methods provides powerful tools to implement strategies for synthesis. Among our interests are new ways to build and cleave carbon-carbon bonds through skeletal rearrangements.
