α-Pyrones and a 2(5H)-furanone from Hyptis pectinata

open access: yesPhytochemistry, 2003
Three pyrones and a 2(5H)-furanone, designated pectinolides D-G, have been isolated from the dichloromethane extract of Hyptis pectinata. The metabolites were characterized on the basis of 1D and 2D NMR spectroscopic techniques. The pyrones were identified as 6S-[3S,6S-(diacetoxy)-5R-hydroxy-1Z-heptenyl]-5S-hydroxy-5,6-dihydro-2H-pyran-2-one (1 ...
