As a newprotectivegroup of amines, 1-isopropylallyloxycarbonyl (IPAoc) group was developed. IPAoc group can be removed by treatment with a palladium-phosphine catalyst forming carbon dioxide and 4-methyl-1,3-pentadiene by the decarboxylation and β-hydrogen elimination of (π-1-isopropylallyl)-palladium intermediate under neutral conditions. The present protection-deprotection was applied to a one-pot

the combination of these two catalytic modes. The key step is a radical/radical cross-coupling between a persistent ketylradical and a transient benzylic or aliphatic C-radical, which is generated through radical cyclization of an oxidatively formed amidyl radical. Several carbamates, amides and sulfonamides containing an alkene moiety and different acyl fluorides can be used as substrates. The resulting
