a known precursor of grandisol (1). The diazoketone 28, on photolysis yielded a mixture of cyclobutane carboxylates 29 and 30. Conversion of the trans acid 31 to a methyl ketone followed by oxidative functionalisation of the phenyl group gave the keto ester 36 which was isomerised under acid catalysis to 37, which in opticallyactive form had been a precursor to (-) grandisol. Photolysis of diazoketone
