ABSTRACT
A simple and original efficient synthesis of 3-amino-1H-isochromene bearing a bromine atom at the C-1 position via a 6-endo-cyclization approach from in situ generated ortho-ynamidyl het(aryl) aldehyde derivatives is achieved under mild reaction conditions and with good yields. Original ortho-ynamidyl benzaldehyde compounds were also successfully obtained.
