| abstract |
PATENT NEW INTERMEDIATES, THEIR PROCESS FOR PREPARATION AND THEIR USE FOR THE SYNTHESIS OF VITAMINS A AND E RHONE-POULENC HEALTH SHORT New intermediates for the preparation of vitamins A and E which are the acetals of the dihalo-5,6 3-methyl-3-hydroxy-hexanal or 6-halo-3-hydroxy-3-methylhexene-5 al or 3-methyl hydroxy-3 hexene-5 al. These intermediates after dehydrohalogenation and dehydration are condensed directly on the .beta.-ionone or on the 2-methyl-heptene-2 one-6 to synthesize vitamins A and E respectively. |
