N-Allyl-1,3-oxazines via a facile keto-ene/cyclization tandem reaction
Brinson, Robert G.,Jones, Paul B.
, p. 6155 - 6158 (2004)
The intramolecular keto-ene/cyclization tandem reaction of γ-N-allylamino ketones is an effective means of producing 1,3-oxazines. The reaction usually requires high temperatures and/or pressures. We discovered that N,N-diallyl amines undergo the reaction
