摘要：
The syntheses of four macrocyclic spermine alkaloids, (+/-)-budmunchiamine A-C (la-c) and (+/-)-budmunchiamine L4 (1), were accomplished by Michael addition of spermine to the ag-unsaturated esters 3a-d, followed by cyclization of the resulting alpha,omega -tetraamino esters 4a-d with triethoxyantimony; N-methylation of the amino lactams 6a-c yielded the budmunchiamines A-C (la-c).
