A novel dealkylation affording 3-aminoimidazo[1,2-a]pyridines: access to new substitution patterns by solid-phase synthesis
摘要:
The three-component synthesis of 5-aminoimidazo[1,2-a]pyridine derivatives has been extended by a novel acid-induced dealkyation reaction that removes the 1,1,3,3-tetramethylbutyl group derived from the isonitrile input. This reaction was conducted on the solid-phase using the HMBA linker and the resulting products subjected to reductive alkylation using several aldehydes, thereby accessing novel substitution patterns at the 3-position.

The tandem oxidative three-component synthesis of two types of the heterocycles such as furans and imidazopyridines, via isocyanides [1+4] cycloadditionreactions in the presence of MIL-101(Cr) under aerobic conditions are reported. When the 4-toluenesulfonylmethyl isocyanide was used, an unexpected [3+2] cycloadditionreaction of isocyanides with aldehydes accomplished and dihydrophenyloxazoles and
