 A new chromone, 7,8-dimethoxy-2-[2-(3'-acetoxyphenyl)ethyl]chromone (1) was isolated from an acetone extract of the Cambodian agarwood along with two known chromones, 6-methoxy-2-(2-phenylethyl)chromone (2) and 6,7-dimethoxy-2-(2-phenylethyl)...
 AbstractN-[2-(œ-Bromoacetyl)phenyl]imides (prepared in two steps from 2-aminoacetophenone) gave upon treatment with sodium azide fused azidoquinolines via an intamolecular cyclization. Reaction of the above azides with phosphines gave N-...
AbstractThe reaction of hydrazones of 2-aminoacetophenone with triphosgene in dichloromethane or benzene in the presence of triethylamine gave quinazolines, pyrazolo[1,5-c]quinazoline and spiro quinazoline dimmers. The latter compounds are being...
 Novel spiro 1,3-benzoxazine dimmers are obtained when hydrazones of 2-hydroxyacetophenone are treated with triphosgene. An X-ray crystal structure and the NMR and MS spectra of these new compounds are reported and discussed.  
AbstractNaturally occurring sesquiterpene lactones from Artemisia species which appeared in the literature during the last six years (1984-1989) have been reviewed.    
 The constituents of the essential oils of two Pulicaria species are reported here for the first time. In addition, the oils of a Pulicaria and five Artemisia species have been analyzed and compared with previous studies
