Abstract: Prostanoic acid [I; u= (CH2)m, m = 0-5, - R3CCR4-, (R3 = / ≠ R4 = H, C1-C5 alkyl, but when X is (CH2)1-3, R3,R4 ≠ H at the same time), V= single bond, O, W = R5CR6 (R5 = / ≠ R6 = 0), C1-C5 alkyl) and its acid salts useful as anticonvulsive, were prepd. by retro-Dieckmann condensation of II to give III, followed by alkali safonification of III, decarboxylating, and then isolating ethers from III.
