摘要

Spiro(cyclopentano-perhydronaphthalene)-3,1'-alkanes (I) are new. Spiro(cyclopentano-perhydronaphthalene)-3,1'-alkanes of formula (I) and their amine salts and esters are new: R1 = H, OH, oxo, 1-12C alkoxy, 2-13C alkanoyloxy, (1-3C alkoxy)methoxy, aryl(2-5C)alkanoyloxy, 2-5C hydroxyalkoxy, SCH2CH2S, OCH2CH2S, 17-spiro-2'-oxirane or (OY,CH2X); Y = H, 1-6C alkyl or 2-13C alkanoyl; X = H, halo, pseudohalogen, CN, 1-6C alkoxy, 2-13C alkanoyloxy or OSO2NR6R7; R6, R7 = H, 1-6C alkyl, 3-7C cycloalkyl or 2-9C alkanoyl; R2 = H, Me or Et; R3 = Me or H if ring A is not aromatic and there is no double bond between C5 and C10 or C10 and C9; R4 = H, OH, oxo, 2-5C hydroxyalkoxy, 1-12C alkoxy, 2-13C alkanoyloxy, (1-3C alkoxy)methoxy, aryl(1-3C)alkoxy aryl(2-5C)alkanoyloxy or OSO2NR6R7; R5 = H, OH, oxo, 1-12C alkoxy, 2-13C alkanoyloxy, (1-3C alkoxy)methoxy, aryl(1-3C)alkoxy aryl(2-5C)alkanoyloxy or OSO2NR6R7; A = an aromatic, partially hydrogenated or saturated ring; n = 1 or 2. An Independent claim is also included for a process for preparing (I).
