Article abstract of DOI:10.3987/COM-93-6536

β-Oxonitriles (1) are easily condensed with cyclic ketones (2a-e) in anhydrous strong acidic conditions to give 1-oxa-5-azaspiro<5.5>undec-2-en-4-ones (3a-e).In the same manner acyclic ketones (2f,g) or aldehydes (2h,i) afford 2,3-dihydro-4H-1,3-oxazin-4-
