  In a one-step alkylation, ring-closure 7-hydroxycoumarins are condensed in acid media with allyl and homoallyl halides or alcohols to linear 6,7-dihydro-2H,8H-benzo[1,2–6:5,4-b']dipyran-2-ones. If both carbon-6 and carbon-8 are unsubstituted in the original coumarin, cyclization to angular isomers 9,10-dihydro-2H,8H-benzo[1,2–6:3,4-b']dipyran-2-ones competes. These compounds are higher ring homologs

  Pyranochromenone derivatives 3a-d, 6a-j and 2H-chromenones 8a-b were synthesized and screened for their in vitro alpha-amylase inhibitory and ABTS(aEuro cent+) [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] free radical scavenging activities. Compounds 3a, 3c, and 6d displayed dual function of ABTS(aEuro cent+) radical scavenging as well as alpha-amylase inhibition. Compound 6h was found to be most potent alpha-amylase inhibitor in present series of compounds. Docking studies suggest that these compounds occupy active site of the human pancreatic alpha-amylase similar to that of acarbose which inhibits enzyme by hydrophobic interactions. These compounds have potential to be developed as therapeutics targeted against diet-induced hyperglycemia in diabetes.Series of pyranochromenone derivatives 3a-d, 6a-j, and 8a-b were synthesized, among these compound 6h shown potent intestinal alpha-amylase inhibitory activity. Compounds 3a, 3c, and 6d were shown dual properties such as alpha-amylase inhibitory and antioxidant activities. These derivatives may serve as a model compounds for design and development of therapeutics based agents.
