Chiral Spirocyclic (Z)-5-Arylmethylene-1,3-oxazine-4,6-diones, New Chiral Heterodienes

A series of (Z)-5-arylmethylene-1,3-oxazine-4,6-diones was synthesized in enantiomerically pure form and found to serve as the attractive alternatives of 6-arylmethylene-1,4-oxazepane-5,7-diones.

CHIRAL SPIROCYCLIC 1,3-OXAZINE-4,6-DIONES AS NOVEL SYNTHONS FOR ENANTIOMERICALLY PURE COMPOUNDS

Chiral spirocyclic 1,3-oxazine-4,6-diones have been synthesized from 1-menthone.Base-catalysed alkylation of the 5-monosubstituted derivatives provides an efficient synthetic method of enantiomerically pure malonamic acids.
