Synthesis of adamantane functional derivatives basing on <Emphasis Type="Italic">N</Emphasis>-[(adamantan-1-yl)alkyl]acetamides

A series of new polyfunctional derivatives was synthesized with use of N-(adamantan-1-yl)alkyl]-acetamides as a starting material. The reactions were carried out in acid media. The obtained compounds could be considered as a building blocks for the synthesis of conformationally restricted peptidomimetics.
