Abstract: Abstract An efficient telescope method for the preparation of furan-2(5H)-one derivatives containing 4H-chromen-4-one fragment was developed. The suggested approach based on tandem multicomponent reaction of 3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one, arylglyoxals and Meldrum’s acid. A distinctive feature of the… read more here.

Abstract: The crystal structures are reported for two unsubstituted arylnaphthalene lactones, 4-phenylnaphtho[2,3-c]furan-1(3H)-one (2), 9-phenylnaphtho[2,3-c]furan-1(3H)-one (3) and a non-aromatic dihydro arylnaphthene lactone, 3a,4-dihydro-9-phenylnaphtho[2,3-c]furan-1(3H)-one (5). There are only minor differences in the geometrical parameters of these structures. However,… read more here.
