Construction of a pentacyclic ring system of isoryanodane diterpenoids by SmI2-mediated transannular cyclization
Autor: Masayuki Inoue, Masaki Koshimizu, Masanori Nagatomo
Publikováno v: Tetrahedron. 74:3384-3390
Isoryanodane diterpenoids possess a densely oxygenated and intricately fused pentacycle (ABCDE-ring), although its unique ring system has not yet been assembled chemically. The 6/5/7-membered BCD-rings of isoryanodanes differ from the 5/6/6-membered

Publikováno v: Angewandte Chemie. 128:2539-2543
Ryanodane diterpenoids structurally share an extremely complex fused ring system, but differ in the substitution patterns of the hydroxy groups. Since these congeners exhibit various biologically important functions, their efficient chemical construc
