The acid promoted rearrangement of syn-1 with HCl led to bicyclic acetal 2 from which enantiopure furan derivative 4 was obtained by hydrogenolysis. The same sequence was applied to anti-1 leading to bicyclus 3 and diastereomeric tetrahydrofuran 5. Treatm

Acid-catalyzed transformations of carbohydrate-derived 3,6-dihydro-2H-1,2- oxazines such as 1, 5 and 13 provided a set of enantiopure furano-1,2-oxazines or pyrano-1,2-oxazines. The reaction conditions determined the degree of solvolysis of the compounds.
