Photocycloaddition of methylcyclobutene to (-)-piperitone affords the photoadduct 3a.Flash vacuum pyrolysis of the photoadduct 3a affords (-)-shyobunone (4a), 2-epi-(-)-shyobunone (5a), 3-epi-(-)-shybunone(6a),2,3-diepi-(-)-shyobunone (7a), and (R)-(+)-is

Shyobunone (I) has been synthesised starting from piperitone (II).The ketone (II) on reaction with divinyllithium cuprate produces stereospecifically the saturated ketone (III) in which the ketone function is masked as the ethylene ketal to give 1,1-ethyl
