✦ Synopsis

The formal amino-Cope rearrangement of a 3-amino-l,5-diene substrate does not proceed solely by a concerted [3,3]-sigmatropic rearrangement mechanism.

There is evidence that Cope Rearrangements may occur by as many as four distinct mechanisms, of which only one is the usual concerted mechanism (1). In 1972, Goldstein and Benzon reported the discovery of a second degenerate rearrangement of 1,5-hexadiene, occurring only at high temperature (250-300

The anionic amino-Cope rearrangement of suitably functionalized acyclic 3-amino-l,5-dicnΒ’ substrates has been achieved and we report the first example of an asymmetric anionic amino-Cope rearrangement to yield an enantiomerically enriched product (75% e.e.).
