Synthesis of 2-amino-2-cyanoadamantane and its derivatives
摘要:
Synthetic routes to new amino nitriles with the functional groups at the 2-position of the adamantane core, based on reactions of adamantanonimines with acetone cyanohydrin or of adamantanone cyanohydrin with aliphatic amines, are considered. The products can be used for preparing new biologically active substances, unsymmetrical adamantyl-containing diamines or amino acids.

A three-component, Strecker reaction of a series of aldehydes or ketones, amines, and trimethylsilyl cyanide for the synthesis of alpha-aminonitriles in the presence of a catalytic amount of a magnetic solid sulfonic acid catalyst, Fe3O4@SiO2@Me&Et-PhSO3H under solvent-free conditions have been investigated. This catalyst, with a combination of hydrophobicity and acidity on the Fe3O4@SiO2 core-shell of the magnetic nanobeads, as well as its water-resistant property, enabled easy mass transfer and catalytic activity in the Strecker reaction. The catalyst was easily separated by an external magnet and the recovered catalyst was reused in 6 successive reaction cycles without any significant loss of activity.
