using silver (I) oxide as the mediator afforded the three O- and C-4 -allyl ethers 3a-c in addition to the diallyl ether 4a. Under basic conditions the tri-O-allyl derivate 4b was produced. The aldehyde group of 1 and 2a and 2b was transformed into the oximes or oximeethers 5, 6a-d, 7, and 8a-c by reaction with hydroxylamine followed by subsequent alkylation or by reaction with methoxyhydroxylamines
