摘要

The syntheses of three bicyclic guanidines as model compounds for the guanidine alkaloid ptilomycalin A are described. The guanidines are prepared from pyrrolidin-2-one via an N- acyliminium ion coupling reaction with silyl enol ethers and a direct guanylation with bis-Boc- thiourea and HgCl2 as the key steps.
