A new and simple method for the synthesis of oxazolines from readily accessible olefins and amidesusing tert-butyl hypoiodite is described; aromatic/aliphatic olefins and amides can be used in the reaction to give a variety of oxazolines.
An efficient catalytic protocol based on reusable MgAl-layered double hydroxides has been developed for the synthesis of multi-functionalized oxazolines via the cyclocondensation of amidines and aminoalcohols. The developed method has a broad substrate scope and excellent functionalgroup tolerance and uses a reusable catalyst. The catalyst can be conveniently recycled by filtration and reused for
A new general route to N-protonated azomethine ylides from N-(silylmethyl)amidines and -thioamides. Cycloaddition of synthetic equivalents of nitrile ylides
