In the presence of excess Bu2BOTf to promote anti-selectivity, an asymmetric aldol reaction with a homochiral terpenoid-derived 1,3-oxazin-2-one as the chiral control element results unexpectedly in ring cleavage by an intramolecular process to form a N-substituted tetrahydro-l,3oxazine-2,4-dione in
