Abstract: Prepn. of beta-carotene with a high 9(Z)-isomer content (formula (I)) is claimed. The 9(Z)- and 9(E) isomers of beta -ionylidenethyl triarylphosphonium salts (formulae II and VI respectively) are sepd. by aq. extn. and crystallisation. (I) may then be obtd. by reacting (II) and (III); or by reacting (II) and (IV) in presence of base to give (V) which is then reacted with (VI) in the presence of base to give (I). X = halide or (HSO4) and Ar = phenyl (opt. substd.). Also claimed is prepn. of (I) by thermal isomerisation of beta-carotene isolated or prepared by known methods.

(V) and (VI) by acid catalysed elimination of the tert. hydroxyl gp., or (A) (ii) the 2,2,6-trimethylcyclohexane-1-one cpd. (II) may be converted directly into the cpd. (VI) by a Wittig reaction with a triphenylmethylenephosphorane cpd. of formula (C6H5)3P=CH2 (VII); (B) converting the cpd. (VI) into the cpd. (V) by acid catalysed isomerisation of the double bond; (C) epoxidising the double bond in the cpd.

(VIII) into the 1,2,2-tri- methyl-cyclopentylmethylketone cpd. (I) by reaction with Lewis acids and opt. splitting off the protective gp. from the O atom. R=H, alkyl, aryl, arylmethyl, trialkylsilyl, triarylsilyl, alkylarylsilyl, alkyloxyalkyl, tetrahydropyranyl, arylmethyloxycarbonyl, alkanoyl or benzoyl residue; M =Li, MgCl, MgBr or MgI.

Abstract: (A) 4-Glycopyranosyloxy-2-methyl -2-buten-1-al derivs. of formula (IVa) and (Va) are new: R4 = CH2OAc or COOMe; Ac = acetyl. (B) Prodn. of retinyl glycosides of formula (I) is effected by (a) reacting an acylated glycoside deriv. of formula (II) with a 4-hydroxy-2-methyl-2 -buten-1-al acetal of formula (III); (b) treating the prod. (IV) with an acid, (c) reacting the resulting aldehdye (V) with a beta-ionylidene -ethyl-triphenyl phosphonium salt of formula (VI) under Wittig conditions; and (d) removing the acyl gps. from the prod.: Z= a linear or branched glycoside gp. comprising 1-20 glycoxide units; Z'=Z in which all OH gps. are replaced by OCOR1; R1 = 1-10C alkyl or aralkyl, R2 and R3 = 1-10C alkyl or 7-10C aralkyl, or R2+R3 = ethylene or propylene opt. substd. by 1-4C alkyl; Y = a leaving gp.; X = a monovalent anion. (C) The use of cpds. (IV) and (V) for prodn. of medicaments is also new.

Abstract: Process for reducing the phosphate content in the effluents from the preparation of salts of ascorbic acid 2-monophosphate, which is characterised in that A. the effluent from the crystallisation of the metal salts of ascorbic acid 2-monophosphate is treated with an alkali metal or alkaline earth metal hypochlorite, chlorine or H2O2 and B. the inorganic phosphate thus obtained by liberation from organically bound phosphorus and/or that still contained in the effluent is precipitated at a pH of 9-12 as sparingly soluble phosphate, in particular as calcium phosphate.
