    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.
