Model studies directed towards microalga polyether toxins. A new approach to the construction of trans, syn, trans-oxotricyclic systems
摘要:
Investigations into the synthesis of trans,syn,trans-oxotricyclic systems present in marine polyether toxins are described. Present studies have led to the development of a scheme for procuring an appropriately functionalized C12 oxane-oxane-oxepane subunit. A new synthetic process for the construction of beta-dialkoxyoxanes starting from beta-diiodooxolanes has been investigated, demonstrating the ability of heterocyclic oxygens to act as conventional neighbouring group participators towards adjacent electrophilic sites.
