PCT No. PCT/US96/18465 Sec. 371 Date Feb. 4, 1997 Sec. 102(e) Date Feb. 4, 1997 PCT Filed Nov. 8, 1996 PCT Pub. No. WO97/17341 PCT Pub. Date May 15, 1997Invented is an improved process for preparing aromatic ring-fused cyclopentane derivatives. Preferred compounds prepared by this invention are indane carboxylates and cyclopentanopyridine derivatives. The most preferred compounds prepared by this invention are (+)(1S,2R,3S)-3-[2-(2-hydroxyeth-1-yloxy)-4-methoxyphenyl]-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid and pharmaceutically acceptable salts thereof and (+)(1S,2R,3S)-3-(2-carboxymethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxypheyl)-5-(prop-1-yloxy)indane-2-carboxylic acid and pharmaceutically acceptable salts thereof. Also invented are novel intermediates useful in preparing these compounds.
