A full FAQ post has been written on meta.chem.SE, explaining the premise of synthesis golf and the 'rules'. Please take a look at this before answering (if you haven't already).
The target of this Easter special round of synthesis golf is tezacaptor, which has recently been approved by the FDA as a treatment for cystic fibrosis in combination with ivacaftor:
- Any commercial starting material is acceptable (as previously, commercial meaning you can buy it from Sigma-Aldrich) providing it has 10 or fewer carbons
- The synthesis must include a cyclopropanation (i.e. the starting materials cannot contain a cyclopropane)
- The synthesis should ideally provide a single stereoisomer of the hydroxyl stereo centre, but to keep things more accessible, a racemic synthesis won't be criticised
