Hitting rewind to predict multi-step chemical reactions

Researchers overcome computational limitations to predict the starting materials of multi-step reactions using only information about the target product molecule

27-Apr-2022

Have you ever only caught the end of a TV show and wondered how the story progressed to that ending? In a similar way, chemists often have a desired molecule in mind and wonder what kind of reaction could produce it. Researchers in the Maeda Group at the Institute for Chemical Reaction Design and ...
