    Abstract: L - (-) - b - (3,4 - Dihydroxyphenyl) - a - methylalanine (" L-a -methyl-DOPA ") is made by splitting a benzyl methyl malonic monoester of the Formula II in which R is CH3 and R1 is CH3, C4H9n or benzyl and, if R1 is CH3, R may also be a benzyl or allyl radical, into its antipodes by means of an optically active base and then (A) converting the D compound of Formula II obtained into an optically inactive symmetrical di-ester by esterification with an alcohol R1OH and then converting into the inactive starting material of Formula II by hydrolysing one ester group, and (B) converting the L-compound of Formula II into the desired L-a -methyl-DOPA by (a) converting into an L-isocyanate (in which R1 is the same as R but cannot be allyl) and thence into an amino compound wherein R2 is a hydrogen atom or an acyl or carbalkoxy radical and splitting off the etherifying radicals R1, the esterifying radical R1 and any N-acyl or N-carbalkoxy group by hydrolysis or, in the case when R1 is benzyl, by hydrogenation and hydrolysis; or (b) when R is an allyl radical, hydrogenating to convert the allyl groups to n-propyl groups, converting the product by known methods, e.g. via the azide, isocyanate and carbamic ester, into an amine of the formula in which R3 is hydrogen or CH3 and splitting off the propyl groups, together with the methyl group R3 if present and any N-acyl or N-carbalkoxy group present, by the action of strong hydrohalic acids; or (c) when R is an allyl radical, converting into the amino compound and treating this by (i) reacting with a hydrohalic acid, or (ii) hydrogenating and reacting with a strong hydrohalic acid, or (iii) splitting off one allyl group together with any esterifying methyl group or N-acyl or N-carbalkoxy group by reaction with an alkali-metal alkoxide and either treating with a hydrohalic acid or hydrogenating and treating with a hydrohalic acid to remove the second allyl group. Symmetrical di-esters of the formula used for the preparation of the mono-ester starting material II are made by condensing a malonic di-ester of the formula CH2(COOR1)2 with 3,4-dihydroxybenzaldehyde or its methyl ethers and hydrogenating and C-methylating the resulting 3,4-dihydroxybenzylidene malonic acid di-ester or corresponding methylated compound. The corresponding 3,4-di-allyl or 3,4-dibenzyl ethers are obtained by allylation or benzylation of the 3,4-dihydroxy benzylmalonic di-esters and the products may, if desired, be re-esterified thus, for example, converting a di-methyl ester into a di-benzyl or di-n-butyl ester.

    Abstract: 1,154,359. Hydrogenated moenomycins. FARBWERKE HOECHST A.G. 2 Sept., 1966 [3 Sept., 1965], No. 39324/66. Heading C2A. The antibiotic activity of moenomycin complex (Specification 977,327) or its components A, B and C against gram-positive pathogenic germs is enhanced by hydrogenation. The hydrogenation is carried out with the aid of precious metal catalysts (e.g. platinum) or Raney nickel in a polar solvent such as water, glacial acetic acid, methanol or dimethyl formamide. In the case of the hydrogenated moenomycin complex, the complex may be separated into the hydrogenated single components A, B and C by the process of Specification 1,126,196. Physical data for the hydrogenated compounds are provided. Pharmaceutical compositions comprise a carrier and a hydrogenated moenomycin complex or hydrogenated component A, B or C.

    Abstract: 1,142,171. Preserving cheese &c. FARBWERKE HOECHST A.G. 16 May, 1966 [17 May, 1965], No. 21565/66. Addition to 1,061,014. Heading A2D. Food, especially hard cheese, is preserved against mould growth by dipping into an aqueous suspension of calcium sorbate which is obtained by reacting an aqueous solution of a sorbic acid salt with an aqueous solution of a calcium salt and which contains 4 to 15% by weight of calcium sorbate. The preferred salts are sodium sorbate and calcium chloride, but potassium sorbate and calcium acetate are also specified.
