Abstract
The highly diastereoselective base-promoted intramolecular cyclization of a variety of enantiopure sulfinyl dienyl amines provides novel sulfinyl tetrahydropyridines that are readily converted to 3-hydroxy tetrahydropyridines via sigmatropic rearrangement. The influence of N- and C- substituents on the process has been studied. Procedures to shorten the sequence such as the tandem cyclization followed by [2,3]-sigmatropic rearrangement, as well as cyclization of the free amine, under Boc- or ArSO- deprotection conditions have been examined. Good to excellent levels of selectivity are generally observed for the reported transformations (dr: 75/25 to >98/2). A novel protocol to access substituted amino dienyl sulfoxides is also reported.

Abstract
Isoxazolo [3,4-a]pyrrolizine and isoxazolo[4,3-c]pyridine are formed by a facile and efficient intramolecular [3 + 2] nitrone cycloaddition, forming two new rings and three contiguous stereocentres with high diastereoselectivity and good yields.
