In continuation of our efforts to develop methods of potential usefulness in the synthesis of Iycopodium alkaloids, we have turned our attention to annotinine I (1). A priori, the best entry into the system of this compound seemed a Beckmann rearrangement of an oxime of the type II obtainable from t

We wish to report the photochemical addition of methyl methacrylate to the compound II. We have chosen this system beoause it is very readily obtainable and can serve both as a model and actual starting material for approaches to a variety of Iycopodium alkaloids. Compound II was obtained\* from th
