摘要:Cosmetic composition which can be applied topically, comprising at least one compound of the general formula (I) in which R 1 is H, C 1 -C 20 -alkyl, cycloalkyl or aryl-C 1 -C 4 -alkyl, n is 1-4, X is —O—, —NH— or —NR 2 — and R 2 H or C 1 -C 20 -alkyl; and at least one compound corresponding to the above formula (I) but in which XR 1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid; use of these compounds and of the composition for stimulating the synthesis of the proteins of the basement membrane; and also both those compounds of the formula (I) in which X is —NR 2 — and both R 1 and R 2 are different from H, and the compounds corresponding to formula (I) but in which XR 1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid, as such.

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.

摘要:Processes for synthesizing new compounds that may usefully be employed in organic synthesis, especially in the synthesis of vitamin A or β-carotene and derivatives thereof, e.g. canthaxanthin, astaxanthin or zeaxanthin are disclosed. The new compounds are especially useful as intermediates (building blocks) in the synthesis of vitamin A or β-carotene, preferably vitamin A.
