Sigmatropic rearrangements defined

A sigmatropic rearrangement is defined as migration, in an uncatalyzed intramolecular process, of a a bond, adjacent to one or more n systems, to a new position in a molecule, with the n systems becoming reorganized in the process. Examples... [Pg.1436]

JV-Alkyl-JV-allyl enamines 128 (X = NR), like their carbon and oxygen counterparts 128 (X = CH2jO), can undergo [3,3]-sigmatropic rearrangement to form y,<5-unsaturated imines 129 (X = NR) (equation 27). This reaction has been defined as a 3-aza-Cope or the aliphatic amino-Claisen rearrangement8. [Pg.908]
