• allow the larger ring system (5,9) to be synthesised. This was accomplished by employing 3-butyn-1-ol and 3-buten-1-ol in place of propargyl and allyl alcohol respectively. The same experimental procedure was used and the three acetals were formed in roughly the same ratio as the previous attempt
