The present invention relates to compounds of Formulas I to IV, their use as activators of long form cyclic nucleotide phosphodiesterase-4 (PDE4) enzymes (isoforms) and to these compounds for use in a method for the treatment or prevention of disorders requiring a reduction of second messenger responses mediated by cyclic 3',5'-adenosine monophosphate (cAMP).

A synthesis of 2-aminobenzoxazoles from the parent C-H compound is described. The procedure involves deprotonation at the 2-position of the benzoxazole and quenching the intermediate organolithium species with a halogen electrophile. The 2-halobenzoxazole is then treated in the same pot with an amine nucleophile to afford the desired product. The substrate scope and selectivity of the reaction are presented. The method is operationally simple and provides access to a variety of amine products bearing additional nucleophilic heteroatoms. (C) 2011 Elsevier Ltd. All rights reserved.
