Use of Conjugated Dienones in Cyclialkylations: Total Syntheses of Arucadiol, 1,2-Didehydromiltirone, (±)-Hinokione, (±)-Nimbidiol, Sageone, and Miltirone
摘要:
Functionalized hydrophenanthrenes can be prepared using a cyclialkylation-based strategy. These annulations are highly dependent on the directing effects of the arene substitutents and on conformational considerations. The utility of this methodology was featured in the syntheses of six diterpenoids.

[EN] Tricyclic heteronaphthoquinone derivatives, that have antineoplastic activity, are disclosed, together with processes for their synthesis. Some of these anti-neoplastics compounds have a saccharide moiety. Some members of this structurally distinct group exhibit activity against multiple drug resistant cancer cells. [FR] Dérivés d'hétéronaphtoquinones tricycliques à activité antinéoplasique, et procédés de synthèse de ces dérivés. Certains de ces composés antinéoplasiques comportent une fraction saccharide. Certains membres de ce groupe structurellement distinct se révèlent actifs contre des cellules cancéreuses résistantes à des médicaments multiples.
