Solid-phase synthesis of Agel 416; a novel approach to modified polyamines
Hone,Payne
, p. 6149 - 6152 (2000)
The synthesis of Agel 416, an acylpolyamine derived from the Spider Agenolopsis aperta, has been achieved on solid support. Stepwise synthesis of the polyamine chain was accomplished using N-protected amino alcohols and the Fukuyama-Mitsunobu reaction. (C) 2000 Published by Elsevier Science Ltd.
