We report the asymmetric amino-Cope rearrangement of some novel 3-amino-1,5-diene substrates to yield enantiomerically enriched 3-alkyl and 3-aryl aldehyde products. We have developed a system that gives excellent and comparable levels of product ena

We report a novel approach to some chiral tetrahydropyran and delta-lactone targets that utilizes the asymmetric amino-Cope rearrangement as a key synthetic step. Products of amino-Cope rearrangement chemistry have also been applied to access piperid
