Microwave-assisted 1,3-dipolar cycloaddition of the azomethine ylide generated by ring opening of a N-vinylaziridine gave new N-vinyl derivatives of pyrrolidine, 3-pyrroline, octahydropyrrolo[ 3,4-c]pyrrole and 1,2,4-triazolidine. Georg Thieme Verlag Stut

A new cycloaddition reaction of quinone imine ketals (QIKs), which could be utilized to the construction of functionalized azaspirocyclics under mild conditions, is described. This transformation involved a [2+2] cycloaddition reaction between QIKs and allenoates catalyzed by DABCO, and then treatment with 1 N HCl in one-pot. The strategy could provide a practical route to access azetidine-fused spirohexadienones in good to excellent yields and with high E -selectivity.

A novel DMAP-mediated Rauhut-Currier/oxa-Michael addition cascade reaction of hydroxylphenyl-substituted para-quinone methide with allenoate was reported for the first time. A series of functionalized chromenes were successfully obtained with moderate to
