Abstract The Diels-Alderreactions of 3-methyl-2-cyclopenten-1-one with simple acyclic dienes under high pressure in combination with EtAlCl2 are described. Angularlymethylated hydrindanones were isolated in reasonably to good yields. Structure analysis of the reaction products by NMR spectroscopy is presented.
