摘要:
Invented is an improved process for preparing aromatic ring-fused cyclopentane derivatives. Preferred compounds prepared by this invention are indane carboxylates and cyclopentano[b]pyridine 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-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid and pharmaceutically acceptable salts thereof. Also invented are novel intermediates useful in preparing these compounds.
