methylimidazole and DBU, the iridium-catalyzed borylation led to formation of allyl boronates, which reacted with aldehydes in a one-pot sequence affording stereodefined homoallylic alcohols. Cycloalkenes without additives as well as acyclic substrates gave vinylic boronates, which were coupled with organohalides in a Suzuki−Miyaura sequence. By this process allylic and vinylic silabutadiene derivatives

This invention relates to solid oral dosage forms of 2R,6R-hydroxynorketamine or prodrugs thereof having Formula Ib, including any pharmaceutically acceptable salt of the foregoing, for use in a therapeutic method for the treatment of a depressive disorder in a patient.
Only cis-1,2-glycols have been obtained by hydroxylation of some 1-arylcyclohex-1-enes. The configuration of these products has been confirmed by infra-redstudies.
