Successive cycloaddition of Δ1-piperidiene 1-oxide to 4H-pyran proceeded regio- and stereo-selectively to afford a 2:1 adduct, catalytic hydrogenation of which gave α-isosparteine in high yield.

Stereoselective syntheses of α-isosparteine
Stereoselective syntheses of α-isosparteine were accomplished by means of 1,3-dipolar cycloadditions. The cycloaddition of nitrone (4) to cyclopentadiene proceeded stereoselectively to afford
2,3,4,5-Tetrahydropyridine 1-oxides. Synthesis and properties (review)
Published data on the synthesis and transformations of 2,3,4,5-tetrahydropyridine 1-oxides are summarized for the first time, classified, and analyzed.
The effects of Lewis acid on the 1,3-dipolar cycloaddition reaction of C-arylaldonitrones with alkenes.
The regio- and stereoselectivity of the 1,3-dipolar cycloaddition reactions of C-aryl-N-alkylaldonitrones (1a-e) with some alkenes were found to be affected significantly by the addition of Lewis
Rotational spectra of tetracyclic quinolizidine alkaloids: does a water molecule flip sparteine?
TLDR
Sparteine is a quinolizidine alkaloid used as a chiral auxiliary in asymmetric synthesis and the structural properties of the O-HN hydrogen bond in the dimer are compared with those of complexes of other secondary and tertiary amines.
