Dispacamide A and new analogs of this marine alkaloid were prepared in seven steps with an overall yield ranging from 12 to 33%. The key step of the strategy was a stereocontrolled Knoevenagel condensation under microwave dielectric heating in the last step. In this condensation, the 2-aminoimidazolin-4-one hydrochloride partners 10a-c were synthesized in three steps with good overall yields (33-79%) via the ring closure of N-guanidino acetic acids 9a-c and the aldehydes 5a,b as the two others building-blocks, in 3 steps with 60-66% overall yields. The six synthetic products have been obtained with a Z geometry about their exocyclic bond on the basis of 13C/1H long-range coupling constants using a gHSQMBC experiment.

A stereoselective synthesis of the marine natural products, polyandrocarpamines A and B, has been achieved using a high-yielding one-step aldol condensation reaction under microwave conditions. The structures of both synthetic compounds were confirmed fol
