Applications of the Vilsmeier Reaction. 13. Vilsmeier Approach to Polycyclic Aromatic Hydrocarbons

Article abstract of DOI:10.1021/jo00339a023

The synthesis of three typical polycyclic hydrocarbons (PAH) has been described, wherein the Vilsmeier reaction plays a major role.Vilsmeier reaction of the tetralol 1 gives the dihydronaphthaldehyde 2 which on cyclodehydration gives the dihydroarene 3.It
