(EN) The present invention features calcilytic compounds. 'Calcilytic compounds' refer to compounds able to inhibit calcium receptor activity. Also described are the use of calcilytic compounds to inhibit calcium receptor activity and/or achieve a beneficial effect in a patient; and techniques which can be used to obtain additional calcilytic compounds.(FR) La présente invention concerne des 'composés calcilytiques', c'est-à-dire des composés pouvant inhiber l'activité du récepteur du calcium. On décrit également l'utilisation de ces composés pour inhiber l'activité dudit récepteur et/ou obtenir un effet bénéfique chez un patient, ainsi que des techniques que l'on peut utiliser pour obtenir d'autres composés calcilytiques.
Formal <i>anti</i>-Markovnikov Hydroamination of Terminal Aryl Alkynes with Pinacolborane and Hydroxylamines via Zr/Cu Sequential Catalysis
We have developed sequential Zr/Cu catalysis involving regioselective hydroboration and electrophilic amination for the formal anti-Markovnikov hydroamination of terminal aryl alkynes. The reaction system can provide a facile access to enamines from terminal acetylenes with high regioselectivity under mild conditions.
