The present invention is a process to make 1-aryl-2-bromo substituted indenes and 1-phenyl-2-bromo substituted indenes that can have different functional groups present around the indene ring and/or the aromatic and/or phenyl ring. The indenes are made using the corresponding 1,2-biaryl-gem-dibromocyclopropane and/or 1,2-biphenyl-gem-dibromocyclopropanes and/or 1-aryl-2-phenyl-gem-dibromocyclopropanes using a metal salts, a solvent, low temperatures.

A procedure for the synthesis of tetrahydroisoquinolines from 2-methyl-1-phenyl substituted indene is described. The process involves the use of osmium tetroxide to cleave the indene double bond forming the keto aldehyde product, which is then combined with a substituted amine forming the substituted isoquinoline. Isoquinolines can be useful as industrial products in the chemical, agrochemical, oil and gas industry, as well as useful as medicaments in the pharmaceutical industry.
