## Abstract The synthesis of 5,6,7,8βtetrahydroβ4__H__βoxazolo[4,5β__c__]azepinβ4βones **5a,b** and 1,3βbenzoxazolβ4βamines **4a,b** are described starting from 4,5,6,7βtetrahydroβ1,3βbenzoxazolβ4βones. Thionation of **5a,b** followed by alkylation with ethyl bromoacetate led to the corresponding _
Acetylation and benzoylation of oxazolo[4,5-b]pyridin-2(3H)-ones, 2-phenyloxazolo-[4,5-b]pyridines and pyrrolo[2,3-b]pyridin-2(2H)-ones were realised via reactions catalyzed with palladium.
