β¦ Synopsis
The synthesis of the cis-fused y-lactone 2,7-dioxabicycle-&3,4 non-4-en-g-one (3) by two routes is reported. Its stereoselective conversion to a key intermediate for pseudomonic acid synthesis is described.

## Abstract An enantioselective synthesis of key intermediates for the synthesis of the antiβmicrobially active pseudomonic acids **A** (**1**), **B** (**2**) and **C** (**3**) is described. DβRibose (**4**) was used as starting material.
A diastereocontrolled synthesis of the tetrahydropyran nucleus of pseudomonic acids has been achieved starting from a chiral building block, which we have developed. The key step is a convex-face reduction of the block having a biased framework which allowed assemblage of the most important core in
