The subject invention provides an expedited synthesis of 5, 6, and 7-iodoindenes from the corresponding aminoindan-1-ones in more than 70% yield, employing readily available precursors and reagents. A three-step sequence involves diazotization-iodination of aminoindan-1-one followed by reduction and dehydration. The method has a general character and can be extended for the preparation of various 4-, 5-, 6- or 7-haloindenes using different halogen sources for diazotization-halogenation reaction.
Synthesis of Isoquinolines from Indenes

A general procedure for the synthesis of isoquinolines from appropriately substituted indenes is described.Ozonolysis of the indenes followed by reductive workup gives intermediate homophthalaldehydes which are treated with ammonium hydroxide to give the isoquinolines.This "one-pot", three-step reaction sequence was applied to the formation of all of the mono-C-methyl-substituted isoquinolines in a regiospecific manner.The procedure is applicable to both electron-withdrawing and electron-donating substituents on the indene system.In this manner the 6- and 7-nitro-,-bromo-, and -iodoisoquinolines were prepared.
