The total large-scale synthesis of argiopine
Formanovsky,Popova,Mikhura
experimental part, p. 752 - 758 (2010/07/15)
The total large-scale synthesis of a natural toxin argiopine, a polymethylenepolyamine derivative, was developed. It consisted of 26 stages and included three key block schemes. Most of the stages proceeded quantitatively, which excluded the necessity of using the chromatographic separation of intermediates.

A facile, one-pot synthesis of Nα-t-Butyloxycarbonyl,Nδ,Nω-di-benzyloxycarbonyl-L-Arginine (3a) and Nα,Nδ,Nω-tri-benzyloxycarbonyl-L-Arginine (3b) is reported.Nα-t-Butyloxycarbonyl-L-Arginine (1b) is treated with trimethylsilylchloride and the tri-silylated intermediate 2c is subsequently allowed to react with benzyloxycarbonyl chloroformate to give 3a in 50percent overall yield.Starting from 1a or 1c, 3b was prepared according to the same procedure in 72percent and 60-85percent yield, respectively.
