Article Synopsis
  • The text discusses a one-pot, microwave-assisted process for creating new dihydro-2'H-spiro[indene-2,1'-pyrrolo[3,4-c]pyrrole]-tetraone derivatives through a three-component reaction involving azomethine ylides and 1-aryl-1H-pyrrole-2,5-diones.
  • The synthesized compounds were tested for their effectiveness against mycobacterial infections and their ability to inhibit acetylcholinesterase (AChE).
  • Notably, compound 4b showed significant antimycobacterial activity, being 12 times more effective than cycloserine, while compound 4h demonstrated strong AChE inhibitory properties

A facile stereoselective synthesis of novel dispiro indeno pyrrolidine/pyrrolothiazole-thiochroman hybrids has been achieved by 1,3-dipolar cycloaddition of azomethine ylides, generated in situ from ninhydrin and sarcosine/thiaproline, on a series of 3-benzylidenethiochroman-4-ones. The synthesised compounds were screened for their antimycobacterial, anticancer and AchE inhibition activities. Compound 4l (IC 1.

A library of novel dispiro compounds containing oxindole pyrrolidine/oxindolopyrrolothiazole-thiochroman-4-one hybrid frameworks has been synthesized in a fully regio- and stereoselective fashion by the three-component 1,3-dipolar cycloaddition of azomethine ylides generated in situ from the condensation of isatins and secondary amino acids (sarcosine/l-thioproline) with 3-arylidenethiochroman-4-ones. This experimentally simple protocol provides good yields of structurally complex, biologically relevant heterocycles in a single operation.
