A convenient, catalyst-free protocol for the quantitative synthesis of fused chromeno[4,3-b]quinolin-6-ones has been developed by simple one-pot reaction of substituted anilines with 4-chloro-3-formylcoumarin using ultrasound irradiation. The protocol offers the advantages of mild reaction conditions, short reaction times and high yields. Indian Academy of Sciences.

Two novel quinoline derivatives e.g. 2-(3-(hydroxymethyl)-7-methylquinolin- 2-yl)phenol (1) and 2-(3-(hydroxymethyl)-6-methoxyquinolin-2-yl)phenol (2) were synthesized. These compounds were characterized by IR, 1H NMR and mass spectroscopy. The
INTRAMOLECULAR CYCLOADDITION REACTIONS INVOLVING NITRILE SULPHIDES

ortho-(Phenylpropioloxy)benzonitrile sulphide, generated in situ by thermal decarboxylation of the oxathiazolone (1), undergoes intramolecular 1,3-dipolar cycloaddition forming the chromenoisothiazole (4a); ortho-cinnamoylbenzonitrile sulphides also yield (4), together with nitrile, chromenoquinoline and amino-chromene by-products.
