Аннотация

The paper reports on the investigation of reactivity of various imines prepared from esters of alanine, phenylalanine and tyrosine, and various aromatic aldehydes in reactions with [60]fullerene. Almost all imines studied were found not to undergo [2 + 3]cycloaddition reactions with C60 under continuous reflux in 1,2-dichlorobenzene because of steric hindrances of the substrates. However, imines of pyridine-2-carboxaldehyde readily reacted with C60 to form corresponding pyrrolidino-fullerenes with moderate yields. The promoting effect of 2-pyridyl group in the [2 + 3] cycloaddition reactions was observed as a result of the formation of intramolecular hydrogen bonds in azomethine ylides formed.
