Trost Ligands

The Trost group at Stanford University has pioneered the use of C-2 symmetric diaminocyclohexyl (DACH) ligands in AAA, allowing for the rapid synthesis of a diverse range of chiral products with a limited number of chemical transformations.

Asymmetric Allylic Alkylation

Palladium-catalyzed asymmetric allylic alkylation (AAA) has proven to be an exceptionally powerful method for the efficient construction of stereogenic centers.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
