Scientists who created tools to build molecules win Chemistry Nobel

German Benjamin List and Scottish-born David MacMillan won the 2021 Nobel Prize in Chemistry on Wednesday for developing new tools for building molecules that have helped make new drugs and are more environmentally friendly.

They share the 10-million Swedish crown ($1.14-million) prize for their separate work on asymmetric organocatalysis, which the award-giving body said was "a new and ingenious tool for molecule building".
