TL;DR: In this paper, the synthesis and antimicrobial activity of 3-(substituted phenacyl)-5-[4'(4H-4oxo-1-benzopyran-2-yl)-benzylidene]-2-4- thiazolidinedione derivatives are described.
Abstract: Synthesis and in vitro antimicrobial activity of some 3-(substituted phenacyl)-5-[4'(4H-4-oxo-1-benzopyran-2-yl)-benzylidene]-2-4- thiazolidinedione derivatives are described. These products were synthesized by the Knoevenagel reaction from 4'-flavone carboxaldehyde and 3-substituted phenacyl-2,4-thiazolidinediones.

TL;DR: The first efficient synthesis of biologically interesting biologically interesting nigrolineabenzopyran A, blandachromene II, and daurichromene D with the benzopyrans moiety has been accomplished using ethylenediamine diacetate-catalyzed reaction as a key step as discussed by the authors.
Abstract: The first efficient synthesis of biologically interesting nigrolineabenzopyran A, blandachromene II, and daurichromene D with the benzopyran moiety has been accomplished using ethylenediamine diacetate-catalyzed reaction as a key step. The key step in these synthetic strategies involves the formation of benzopyran moiety via an electrocyclization reaction.
