This paper describes a highly efficient intermolecular biomimetic polyene cyclization method using acetal as initiators. Both good yield and asymmetric induction were obtained. Copyright
CYCLISATION PROCESS OF FORMING A MULTIPLE RING COMPOUND
-
Page/Page column 4; 45; 57-58, (2010/11/28)
The present invention relates to a cyclisation process of forming a multiple ring compound from an isoprenoid compound. The cyclisation process involves reacting the isoprenoid compound with an acetal initiator under conditions sufficient to form the multiple ring compound. The isoprenoid compound is contacted with an initiator an optionally with a catalyst. Cyclisation occurs by reaction of the initiator with the isoprenoid compound. Cyclic aceta compounds wherein the acetal forms part of 6-membered unsaturated ring are also defined.
