Chiral Boronic Esters Coupled

Canadian researchers report the first example of cross-coupling chiral secondary organoboranes with retention of stereochemistry
Department: Science & Technology

ACS MEETING NEWS A powerful way to form C–C bonds is by way of transition-metal-catalyzed cross-coupling reactions employing air- and moisture-tolerant organoboranes. But examples of successful coupling reactions with secondary organoboranes are rare, and chiral versions are rarer still. Cathleen M. Crudden of Queen's University, in Kingston, Ontario, has now devised the first example of the cross-coupling of chiral secondary boronic esters that proceeds with retention of stereochemistry (J. Am.
