Rhodium (II) acetate-catalysed cyclisation of α-diazoketones derivedfrom 3-arylpropionic acid produces bicyclo[5.3.0]decatrienones or 2-tetralones depending on the substitution pattern of the aryl ring: the former products are transformed into the latter by catalytic amount of trifluoroacetic acid.

short new azulene synthesis, requiring no dehydrogenation step, has been developed (Scheme I). Intramolecular carbene addition creates the bicyclic ring system of azulene with a high degree of unsaturation and versatile functionality in a single step from a simple benzene derivative. The synthesis is particularly amenable to preparation of specific /sup 13/C- and /sup 2/H-labeled azulenes.
