Aminoalkylbenzotriazoles: reagents for the aminoalkylation of electron rich heterocycles
摘要:
Secondary and tertiary aminoalkylbenzotriazoles react with pyrrole, indole, their N-methyl analogs and with 2-methylfuran under mild reaction conditions in the presence of a Lewis acid to afford selectively the corresponding secondary or tertiary amines.

with dichloro(dimethyl)- and trichloro(methyl)-silanes, but whereas chlorotrimethylsilane interacts with α-amino ethers to yield iminium salts, the reaction of the latter silane with aminals does not: in situ Mannich reactions may be carried out using these systems, and in the case of the reactions using chlorotrimethylsilane and aminals the reactions can be catalytic with respect to the silane.
