چکیده

Benzodioxane represents a series of synthetic and natural compounds of considerable medicinal importance. Compounds containing dioxane ring systems exhibited different biological activities such as antihepatotoxic, -adrenergic blocking agent, neuroleptic, anti-inflammatory, hypolipidemic and D 2 antagonist/5-HT 1A partial agonist activity. The literature concerning chemistry of benzodioxanes chemistry is scattered and has not been reviewed so far. The present article covers the various methods of preparing 1, 3-and 1, 4-benzodioxane ring system, different chemical reactions, and their different biological activities.  2008 Trade Science Inc. -INDIA

Copper-catalyzed tandem process: an efficient approach to 2-substituted-1,4-benzodioxanes.

An efficient method for the preparation of various 2-substituted-1,4-benzodioxanes by CuBr-catalyzed tandem reactions of 2-((o-iodophenoxy)methyl)oxiranes with phenols has been developed. The reaction involves the ring-opening process of 2-((2-iodophenoxy)methyl)oxirane followed by an intramolecular C-O cross coupling cyclization.

Dual catalysis by Cu(I): facile single step click and intramolecular C-O bond formation leading to triazole tethered dihydrobenzodioxines/benzoxazines/benzoxathiines/benzodioxepines.

Dual copper catalysis, involving two different reactions, click (alkyne-azide) and carbon-oxygen bond formation (aryl iodide-secondary alcohol) in a single step, is reported. Synthesis of novel benzodioxines (benzodioxanes), benzoxazines, benzoxathiines and benzodioxepines, which feature benzo-condensed six or seven membered rings containing two hetero-atoms attached to a 1,2,3-triazole, is des...
