Abstract

A versatile and convenient one-pot direct approach to 2, 3-disubstituted benzo/naphtho [b] furans via domino annulation of α-oxoketene dithioacetals and 1, 4-benzo/naphthoquinone has been achieved in the presence of aluminium chloride at room temperature. This protocol represents an extremely simple, straightforward and rapid entry to highly substituted benzo/naphtho [b] furans in good yields from easily viable starting materials under mild ...
