The interaction of isatins, α-amino acids and 1,6-bismaleimidohexane has been studied. It was found that for 1'-R3-2'-R2-3'-R1-5'-(6-{1'-R3-2'-R2-3'-R1-2,4',6'-trioxo-1,2,3',3'a,4',5',6',6'a-octahydro-2'H-spiro[indole-3,1'-pyrrolo[3,4-c]pyrrole]-5'-yl}hexyl)-1,2,3',3'a,4',5',6',6'a-octahydro-2'H-spiro[indole-3,1'-pyrrolo[3,4-c]pyrrole]-2,4',6'-triones were formed through three-component 1,3-dipolar cycloaddition of azomethine ylides generated in situ by the decarboxylative condensation of isatin and some α-amino acids with dipolarophile 1,6-bismaleimidohexane. This method has the advantages of mild reaction conditions, high atom economy and excellent yields. The most suitable conditions for this reaction are boiling alcohol-water medium. The obtained compounds showed a weak selective antimicrobial activity for the Micrococcaceae family.
