Abstract
Abstract: The formation of imines from acetals and primary amines can be carried out at significantly lower temperatures using scandium or lanthanide triflates as catalysts, than in the absence of a catalyst: the intermediate aminol ethers can also take part in cascade cyclisation reactions, for example using tryptamine and ethyl tryptophanate.
