Production of γ-acetoxytiglualdehyde |
| abstract |
(57) [Summary] (Correction) [Structure] General formula HC≡C—C (CH 3 ) (OH) —CH═C (R) 2 The pentenin-3-ol of II was converted to a lower alkanol, R 1 O. 2-Hydroxy-2-methyl-3-butynal of the formula HC≡C—C (CH 3 ) (OH) —CHO III thus obtained by selective ozonolysis in H, as well as general by-products formula Of 1-alkoxyalkyl hydroperoxide and catalytic hydrogenation (in the case of 2-hydroxy-2-methyl-3-butynal of formula III hydrogenated is optional), the formula H 2 C = CH-C ( CH 3 ) (OH) -CHO V of the known 2-hydroxy-2-methyl-3-butenal, which is obtained in a manner known per se in the formula CH 3 COO—CH 2 CH═C (CH 3 ) —CHO I Of γ-acetoxytigglualdehyde -A method for producing acetoxytigglualdehyde. [Wherein both Rs represent hydrogen or methyl, and R 1 represents C 1-4 alkyl] [Effect] The starting material for the production of vitamin A acetate can be produced by a simple method. |
