Abstract
The sesquiterpenoid (+)‐myomontanone (2), a toxic component of the Australian plant Myoporum montanum, has been synthesized through a short efficient sequence. An electrochemical oxyselenation‐deselenation sequence allows oxidation of an intermediate olefin, in the presence of the furan ring, ultimatively providing the requisite enone of the natural product. This approach also allowed synthesis of (+)‐10,11‐didehydromyomontanone (13) and several other natural products of this family of furanosesquiterpenoids.

## Abstract A simple and highly efficient stereoselective total synthesis of (11__β__)‐11‐methoxycurvularin (**5**), a polyketide natural product, was achieved. The synthesis commenced with a Cu‐mediated regioselective opening of (2__S__)‐2‐methyloxirane (**6**) and comprised a __Keck__ asymmetric
