Abstract

Abstract Sodium hydrogen sulphate (), n-tetra butyl ammonium bromide (TBAB) as a phase transfer catalyst (PTC) in water, and 1-butyl-3-methyl imidazolium hydrogen sulphate [bmim] as ionic liquid (IL) has been used as a mild reaction promoter for the cyclocondensation of formalin,-naphthol and aromatic amines to afford respective 2, 3-dihydro-2-phenyl-1H- naphtho-[1, 2-e][1, 3] oxazine derivatives. The present protocols are greener, high yielding ...
