Preparation of (9Z, 11Z) - Vitamin A

Starting from (7E,9Z)-C15-aldehyde 4, the syntheses of (9Z, 11Z)-vitamin A acetate and palmitate are reported. The construction strategy is based on treatment of 4 with Zn-PPh3/CBr4, addition of acetaldehyde followed by a

Synthesis of retinals isotopically labelled at positions 11, 12, 14 and 20

Five retinals, having different combinations of 2H, with one having 2H and 13C labels at positions 11, 12, 14 and 20, were obtained with a chemical purity of above 98percent, a level of 2H enrichment greater than 95percent and with 13C enrichment of 99per
