The mass spectrum showed molecular ion peak at m/z 277 for compound 5, at m/z 279 for compound 6a and at m/z 351 for compound 6b. The 1H NMR of compounds 18 and 20 showed presence of the phenolic (OH) at δ 10.8 ppm and δ 11.2 ppm as broad peaks, respectively, which it disappeared in compound 19.	cache/eurjchem-1369.pdf	txt/eurjchem-1369.txt
