标 题 :Synthesis of Vitamin A, intermediates and conversion thereof to Vitamin A
发明人：OROSHNIK WILLIAM
权利人:SCM CORP
摘要:A synthesis of novel Vitamin A intermediates from beta-ionone is described as well as a conversion of the intermediates to Vitamin A. The length of the conjugated aliphatic side chain of beta-ionone is increased while still ultimately obtaining the desired trans form of Vitamin A. In general, beta-ionone is ethynylated to ethynyl-beta-ionol, the hydroxyl of which is etherified to form an ethynyl-terminated, alkoxy-substituted, beta-ionol intermediate. The intermediate is coupled through its copper derivative with a compound like chloro-isopentenyl acetate to produce a C20 skeleton. By semi-hydrogenation, the acetylenic bond on the C20 skeleton is converted to an ethylenic bond, and by hydrolysis the terminal ester moiety is converted to a hydroxyl group. Treatment with a strong base removes the alkoxy group to produce Vitamin A.

标 题 :Synthesis of 1,2-dioxetanes and intermediates therefor
发明人：BRONSTEIN IRENA Y; EDWARDS BROOKS
摘要:Compounds having the formula: n wherein T is a polycycloalkylidene group (e.g., adamant-2-ylidene); R is a C 1-20 alkyl, aralkyl or cycloalkyl group; and Y is a fluorescent chromophore (e.g., n m-phenylene), produced by reacting a compound having the formula: n with an R-ylating agent (e.g., R 2 SO 4 ) in the presence of an alkali metal alkoxide in a polar aprotic solvent. Also, compounds having the formula: n are produced by reacting a compound having the formula: n with n wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula n are produced by reacting a compound of the formula n with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups. The aforementioned compounds and procedures are useful in the synthesis of enzyme-cleavable 1,2-dioxetane ring systems that can serve as members of a binding pair employed, for example, in chemiluminescent immunoassays, DNA probe assays, and direct assays for an enzyme.

标 题:Use of alpha-di(lower alkoxy) anthraquinones in the synthesis of Alizarin Saphirols
发明人：WHITE DAVID L; FITZPATRICK JOSEPH W
权利人:TOMS RIVER CHEMICAL CORP
摘要:Alpha-dihydroxyanthraquinones used as intermediates in the synthesis of many dyestuffs, such as the Alizarin Saphirols (e.g. Color Constitution No. 63000, 63005, 63010, 63011, 63315 and 63610) can be replaced on an equimolar basis by alpha-di(lower alkoxy)anthraquinones. The alpha-di(lower alkoxy) anthraquinones can be converted in a single step, by treatment with oleum, to the corresponding alpha-dihydroxyanthraquinone-beta-disulfonic acids in almost quantitative yield. The corresponding diamine is obtained by dinitrating followed by reduction of the nitro groups. The known intermediate, leuco 1,4,5,8-tetrahydroxyanthraquinone (see C.I. No. 62500) can be obtained either by reduction of the diamine or by reduction of the dinitro compound. In one embodiment, the alpha-di(lower alkoxy)anthraquinone is obtained from dinitroanthraquinone by treatment thereof with methanol and KOH.

摘要:The compounds of the formula I (I) in which A denotes N or N->O, Z denotes O or NH, R denotes H, (halo)alkyl, (halo)alkenyl, (halo)alkynyl or alkoxycarbonyl, R1 denotes hydrogen, halogen, amino, -NHOH, hydroxyl, (substituted) phenylazo or a radical of the formulae Y=C=N-, Y1Y2C=N-, Y3NH- or K denotes 0 or 1, and m and n, independently of one another, denote a number from 1 to 4, with the proviso that, when Z-R denotes OH or NH2, (R1)n denotes at least one radical of the formula or represents two radicals, in the 5 or 6 position of the heterocyclic ring, which, in the 5 position, denote halogen and, in the 6 position, denote a radical of the group comprising halogen, amino, hydroxyl or phenylazo, which may be substituted as specified above, are valuable intermediates in the synthesis of plant protection agents.
