Thermolysis of the 2,5-bis(trimethylsiloxy)tricyclo2,5>decan-7-ones 3 leads to perhydroazulenes by a transannular reaction involving an oxygen to oxygen migration of a silyl group in the intermediate cyclodecadienones.This 3-step transf

Boron trifluoride-catalyzed allylic rearrangement of the cyanophosphates of α,β-unsaturated ketones (1a-d, 7 and 14) was found to give the allylic phosphates (3a-d, 9 and 16), which were successfully converted to β-cyano-α,β-unsaturated ketones (6a-d, 13 and 20) by acid hydrolysis (0.5 N HCl) followed by manganese dioxide oxidation of the resulting allylic alcohols(5a-d, 11, 12 and 17).The stereochemical features of the allylic phosphates (9 and 16) are discussed.Keywords-α,β-unsaturated ketone; diethyl phosphorocyanidate; cyanophosphate; allylic rearrangement; boron trifluoride etherate; manganese dioxide; β-cyano-α,β-unsaturated ketone
