Michael T. Crimmins

American organic chemist, professor emeritus in the Department of Chemistry of the University of North Carolina at Chapel Hill.

He developed the asymmetric aldol additions of the titanium enolates of N-acyloxazolidinethiones and N-acylthiazolidinethiones, which give either of the two syn aldols with the same auxiliary simply by changing the amount of base, and applied them to the total synthesis of complex natural products.
