==Production of indane skeleton== Indane itself is usually produced by hydrogenation of indene. More complex indanes are produced by cyclization of phenylpropionic acid and related compounds under Friedel-Crafts reaction conditions. Such routes afford 1-indanone, which can be reduced to indanol or the indane. 2-Bromoaryl derivatives with unsaturated substituents undergo Heck reactions (palladium-catalyzed) involving formal loss of HBr and cyclization to indanes and indenes. Enantioselective routes to chiral indanes and indenes are also available. Routes to the hydroindanes are also relevant.
