## Abstract The synthesis of 5,5,10,10‐tetramethyl‐1‐oxacyclotridecan‐6,7,8,9‐tetrone (12) was achieved via a multistep procedure involving an oxidation known as the Rubottom reaction. The key intermediates were the dialdehyde (25), the diacid (33), the cyclic diketone (39) and the bis(silyl enol e

Fifteen title compounds, e.g. (I)-(III), are prepared essentially as described previously. Evaluation of their absorption, emission and laser properties shows that N-allyl substituted derivatives (Ia) and (IIa) have high fluorescence quantum yields and laser efficiencies of 137 and 140%, respectivel
