Convenient synthesis of the 1,4-bishomo-6-secoheptaprismane ring system
摘要:
The facile synthesis of 13, a highly functionalized 1,4-bishomo-6-secoheptaprismane, is reported in 45% overall yield, starting with the Diels-Alder adduct of 5,5-dimethoxy-1,2,3,4-tetrachlorocyclopentadiene and p-benzoquinone. Initial attempts to functionalize 13 for subsequent transformation to hexaprismane (1) are summarized.

Synthesis of bishomohexaprimanedione, the D2h dimer of norbornadienone and a potential precursor to hexaprismane, is reported. The synthesis includes an unusual ring contraction of a cycloalkene using a cis-hydroxylation/periodate cleavage/aldol sequence. The structure of bishomohexaprimanedione determined from single crystal x-ray analysis is well reproduced by ab initio calculations.
