A C(sp2)–C(sp2) bond can be constructed via a photoredox/N-heterocyclic carbene (NHC)-cocatalyzed radical cross-couplingreaction, which provides a complementary strategy to classic electron pair processes. The present protocol represents the first example of an NHC-catalyzed two-component radical cross-couplingreaction involving C(sp2)-centered radical species. The decarboxylative acylation of oxamic

New N,N-di-alkyl- or alkenyl-substituted derivatives of oxamic acid of which the two alkyl or alkenyl groups are different from each other are now produced and found to exhibit the cerebral protective effect against cerebral anoxia in brain of a mammalian animal, including human, and to be useful as an agent for improving or ameliorating the damaged or disturbed functions of the brain. Some known N,N-di-alkyl-substituted derivatives of oxamic acid of which the two alkyl groups are identical to each other are now also found to have similar, cerebral protective effect against cerebral anoxia and to be useful as an agent for improving the damaged functions of the brain.
