Substituted benzyl alkynyl ethers, prepared from the corresponding α-alkoxy ketones in a two-step sequence involving enol triflate formation and KOtBu-induced E2 elimination, undergo [3,3]-sigmatropic rearrangement/ intramolecular 5-exo-dig cyclization at 60 °C to form substituted 2-indanones in good overall yields. 1,3-cis-Disubstituted-2-indanones are formed preferentially when the benzylic substituent R1 is bulky. Substituted indenes may be prepared from 2-indanones in high yields by Horner-Wadsworth-Emmons reaction.

The ozonolysis of a series of disubstituted (1,2 and 1,3) and trisubstituted (1,2,3) indenes 1-28 in carbon tetrachloride at 20 deg C has been investigated.The major product in each case was the corresponding bicyclic ozonide, usually obtained as a mixtur
