Abstract:
The transmetallation of 3-stannylated enamines,3 1-morpholino-3-(trialkylstannyl)cycloalk-1-enes and 3-morpholino-5-(tributylstannyl)hex-3-ene, with butyllithium is a new and general way to generate 1-aminoallyllithium compounds. Stabilization by aromatic substituents is not further necessary as in the case of preparation by deprotonation and even the thermodynamically less stable exo-amino derivatives are accessible. Therefore homoenolate-equivalents of cyclic ketones are made available. Thus, the corresponding 3-alkylated or 3-silylated cycloalkanones and alken-3-ones were prepared via the 1-morpholinoallyllithium compounds.
