Secondary boranes and boronic esters can be prepared by homologation of boranes and boronic esters using Hoppe‐type lithiated carbamates. As described by V. K. Aggarwal and co‐workers on pp. 7491 ff., iterative use of this new, broad‐ranging methodology allows either enantiomer of either diastereomer to be easily accessed, as depicted in the cover picture. The background photograph “Dusk on Upper Geraldine Lake” was taken in Jasper, Alberta, Canada by Barry Parisien (www.barryparisien.com).
