ChemInform Abstract
Bromination of the dihydrophenalenone (I) followed by reaction with sodium azide (II) yields the α-azido ketone (III). This compound as well as the literature-known azido ketone (VIII) are metalated by means of sodium hexamethyldisilazide and then treated with the mixed anhydride (IV) to give the (formyloxy)vinyl azides (V) and (IX) respectively which cyclize upon reaction with triethyl phosphite, forming the triazoles (VI) or (X). The N-formyltriazole (VII) is obtained upon quenching the reaction of (V) with triethyl phosphite after a short time.
