Novel, intramolecular 1,3-dipolar cycloadditions of azomethine ylides have been applied to the synthesis of functionalized core structures of the stemofoline alkaloids. In an effort to maximize the efficiency of this key transformation in the context of an eventual totalsynthesis of these complex natural products, a number of strategic modifications to the cycloaddition substrate were investigated. The
