  • Asymmetric synthesis of 5- and 6-membered lactones from cyclic substrates bearing a C2-chiral auxiliary
    作者:Yukio Yamamoto、Akio Sakamoto、Takaaki Nishioka、Junichi Oda、Yoshimasa Fukazawa
    DOI:10.1021/jo00003a038
    日期:1991.2
    Optically active lactones were synthesized by a novel asymmetric synthesis in which enantiotopic groups remote from a prochiral center were effectively discriminated. The cyclic diamide alcohols bearing a C2-chiral auxiliary, (+)-[1,1'-binaphthyl]-2,2'-diamine (4), were designed and prepared such that the hydroxyl group should attack preferentially at one of the two carbonyl groups. By the catalytic action of trifluoroacetic acid, the substrates 6a,b and 19 were smoothly converted to the lactones 7a (71% de), 7b (97% de), and 20 (> 99% de), the configurations of which were determined to be R, S, and R, respectively. A naturally occurring pheromone, (R)-(+)-5-hexadecanolide (13), was synthesized optically pure from 7b. Transition-state models for the present asymmetric lactonization were constructed according to the stereoelectronic theory proposed by Deslongchamps. The stability of the models was assessed by MM2 calculation, and the direction of asymmetric induction thus calculated coincided with the experimental results.

  • Copper-Catalyzed Desaturation of Lactones, Lactams, and Ketones under pH-Neutral Conditions
    作者:Ming Chen、Guangbin Dong
    DOI:10.1021/jacs.9b07932
    日期:2019.9.18
    A copper-catalyzed desaturation method is reported, which is suitable for converting lactones, lactams and cyclic ketones to their α,β-unsaturated counterparts. The reaction does not require strong base/acid or sulfur/selenium reagents, and can be carried out through a simple one-step operation. The protocol uses inexpensive catalysts and reagents, exhibits excellent scalability and functional group
