    Abstract: Analgesic pyrrolidine derivs. (I; R1 = pyridy1; R2 = H, lower alky1; R3 = H, lower alky1, benzy1; R4 = halogen, lower alcohol, lower alkoxy, nitro, and amino-substituted pheny1) were prepd. by the redn. of pyrrolines II. Thus, 4-methy1-4-nitro-3-(4-pytidy1)-valerophenon was reduced by Zn in CH3COOH followed by treating with 1n-HC1 and crystallizing with EtOH/(CH3)2CO gave trans-4-(2,2-dimethy1-5-pheny1-pyrolidy1)-pyridine dihydrochloride. I are useful as non-addictive analgesic agent, 3.0g., racemic 4-(cis-2,2-dimethy1-5-pheny1-3-pyrrolidiny1)-pyridine dihydrochloride had ED50 47mg/kg.

    Abstract: Title compds. (I; R1 = 2-thienyl or phenyl substuted with lower t-amino group, R2 and R3 are independently, H or lower alkyl; R4 = halogen, lower alkyl, lower alkoxy, nitro, phenyl), useful as anaesthetics, were prepd. by reduction of compd. II in the presence of catalyst. Thus, 17 g 2-(P-methoxy-phenyl)-5, 5-dimethyl-4-(2-thienyl)-1-pyrroline and 10 g sodium borohydride were reacted in 250 ml anhydrous ethanol gor 6 hr with N2 gas to give cis-5-(p-methoxyphenyl)-2, 2-dimethyl-3-(2-thienyl)-pyrrolidine hydrochloric acid salt (m.p. 180oC).

    Abstract: Oxetanones of formula (I) and their salts with weak acids are new: R1 and R2 = 1-17C alkyl (opt. having up to 8 double or triple bonds and opt. interrupted by an O or S atom which is not alpha to an unsatd. C atom), phenyl, benzyl or -C6H4-X-C6H5, all opt. ring-substd. by 1-3 1-6C alkyl, alkoxy or alkylthio; X = O, S or (CH2)m; m = 0-3; R3 = H or 1-3C alkyl or alkanoyl; R4 = H or 1-3C alkyl; R5 = H, Ar or Ar-(1-3C) alkyl or is 1-7C alkyl, opt. interrupted by Y and/or substd. by Z; or R4 and R5 together make a 4-6 membered satd. ring; Y = O, S, NR6, CONR6 or NR6.CO; Z = OR7, SR7, NR7R8, CONR7R8 or NR7.COR8; n = 0 or 1, and if 1 then R5 = H; Ar = phenyl, opt. substd. by up to 3 R9 or ORa; R6, R7, R8 and R9 = H or 1-3C alkyl. Where R3 = HCO and R5 = isobutyl, or R3 = MeCO and R5 = carbamoylethyl and also R2 = undecyl or 2,5-undecadienyl and R1 = n-hexyl, then R4 is not H. Also new are ethanol derivs. (III): when R1 = n -hexyl and R2 = undecyl or 2Z,5Z-undecadienyl, at least one asymmetric C atom in the ring or in beta-position to the ring has the R configuration. -
