    Abstract: Prepn. of E-oxime-ethers of phenylglyoxylic acid esters of formula (I) comprises (a) reacting a phenol Xm-Ph-PH in a base in the presence of a solvent to give a phenolate; (b) mixing with a lactone of formula (III); (c) distilling off solvent and reacting the mixt. at 50-250 deg.C in the melt; (d) washing with water and acid to give a 2-phenoxymethylbenzoic acid of formula (IV); Q = OH); (e) treating with phosgene or SOCl2 to give the 2-phenoxymethylbenzoyl chloride (IV; Q = Cl); (f) reacting with alkali(ne earth)metal cyanide opt. in the presence of prussic acid; (g) treating the 2-phenoxymethylbenzoyl cyanide (IV; Q = CN) with MeOH in the presence of acid to give (VIIb); (h) opt. splitting under acidic conditions to give (IV; Q = C(O)NHR) or (i) treating (IV; Q=R) with dimethyl sulphoxide in the presence of a base to give a beta ketosulphoxide (IV; Q = CH2SOCH3) and treating with a halogenating agent, and MeOH in acid to give (IV; Q = C(O)OMe); (k) reacting (IV; Q = C(O)OMe) and/or (VIIb) with O-methylhydroxylamine or its acid addn. salt to give (I). Q = R1CH2SOMe, OH, Cl, CN or C(O)NNR; X, Y = halo, 1-4C alkyl, 1-4C alkoxy or CF3; m = 0-4; n = 0-3; R = 1-4C alkyl.

    Abstract: The muscone of the formula I is prepared by bringing open-chain 2,15-diketones of the general formula II CH3-CO-X-CO-CH3 (II> in which X represents one of the radicals -(-CH2-)@(a> -CH=CH-(-CH2-)@CH=CH- (b> -CH2-CH=CH-(-CH2-)@CH=CH-CH2- (c> -CH2-CH2-CH=CH-(-CH2-)@CH=CH-CH2-CH2- (d) or -CH2-CH2-CH2-CH=CH-(-CH2-)@CH=CH-CH2-CH2-CH2- (e), into contact at temperatures of 300 to 400 DEG C in the presence of 5 to 15 % by weight of water, relative to the amount of catalyst, in the gas phase over a fixed-bed catalyst which contains TiO2, CeO2 or ThO2 as the catalytically active compound and hydrogenating catalytically the unsaturated cyclic ketone formed in this reaction by intramolecular aldol condensation. Furthermore, the open-chain unsaturated ketones of the formulae IIb, IIc and IId and advantageous processes for their preparation and their use as intermediates for a simple industrial muscone synthesis are claimed.
