Abstract

Rhodium (II) acetate-catalysed cyclisation of α-diazoketones derived from 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.
