✦ Synopsis

The viability of the key steps in our approach to the novel sesquiterpene breynolide (1) has hem verified by preparation of the hydrobenzothiophene 16. The sequence features a Diels-Alder reaction of 10 with 7 to load eventually to 13; subsequent dipolar cycloaddition of 13 with a functionalized nitrile oxide gave 16.
