| Popis: | 92 1.Chiral Syn-Aldol Reaction Studies of Chiral γ-Benzyloxy Subsituted Vinylogous Urethane Chiral γ-benzyloxy subsituted vinylogous urethane 1 was deprotonated and reacted with aldehyde to form syn-aldol adduct, the selectivity of this product was analyzed using chiral column to determine their enantio- selectivity and diastereoselectivity. 2.Chiral [2,3]-Wittig rearrangement Reaction Studies of Chiral γ-Allyloxy Subsituted Vinylogous Urethane Dienolates of various chiral γ-allyloxy subsituted vinylogous urethane undergo a [2,3]-Wittig rearrangement to generate various 5-alkenyl-4- pyrrolidine-1-yl-5H-furan-2-one type compounds. The study of the conditions to afford superior enantioselectivity and diastereoselectivity was conducted accordingly. |
