In contrast to the recent breakthrough in electrochemical C–H aminations, the electrochemicallyoxidative C–N bondformation through a C–C bond cleavage is rarely studied. This work describes an electrochemical C–C amination of alkylarenes for the efficient synthesis of versatile anilines, as well as carbonyl compounds. With the cheap and durable graphite plates as electrodes, and in a simple undivided
The direct preparation of mannosyl[2]rotaxane derivatives by O-glycosylation from tetra-O-acetyl-alpha-D-mannosyltrichloroacetimidate and a tert-butylanilinium alcohol in the presence of dibenzo-24-crown-8 is described. The method appears to be very efficient and allows for the preparation of either orthoester or mannosyl rotaxane derivatives, depending on reaction conditions.
