A method of synthesis is provided to obtain a range of UV absorbing compounds. The method broadly involves(a) the reduction of a glutarimide or its reaction with a carbon nucleophile; (b) when step (a) is a reduction, exposing the product of step (a) to an acidic environment to form a cyclic amide; (c) reducing the product of step (a) or step (b) to form a corresponding enamine; and subjecting the enamine product of step (c) to an acylation.

The present invention describes compounds and uses thereof in applications relating to absorption of electromagnetic energy. Preferred compounds are double bond-containing cyclic compounds capable of absorbing electromagnetic radiation energy and having improved photostability due to the presence and location of one or more fluorine groups in relation to the double bond of the ring.
