An inverse electron-demand aza-[4+2] cycloaddition reaction of allenamides with 1-azadiene is described here. Effects of solvents on diastereoselectivity along with synthetic scopes and mechanistic insights are illustrated. Despite some synthetic limitations, this aza-[4+2] cycloaddition does provide a useful template for the synthesis of aza-glycoside related heterocycles.

(Chemical Equation Presented) A detailed account on the stereoselective synthesis of the C1-C9 subunit of (+)-zincophorin is described here. This approach features the first application of a stereoselective inverse electron demand hetero-[4 + 2] cycloaddi
