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 reaction conditions.
