Synthesis of a 2,7-Dioxatricyclo[4.2.1.03,8]nonane: A Model Study for Possible Application in a Synthesis of Dictyoxetane
摘要:
A method for the synthesis of the 2,7-dioxatricyclo[4.2.1.0(3,8)]nonane ring system characteristic of the marine diterpene dictyoxetane has been developed. This method utilizes a dipolar cycloaddition of a 3-oxidopyrylium salt to create the carbon skeleton (Scheme 1) and employs an intramolecular S(N)2 displacement to form the oxetane ring (Schemes 9, 10, 13). The route described could easily be adapted to incorporate additional functionality, making it potentially useful in a total synthesis of dictyoxetane.
