This article presents selective transformations of some readily available cyclodienes through simple chemical procedures into novel functionalized small-molecular entities. The syntheses hereby described involved selective cycloadditions, followed by ring

– We have synthesized a new class of N-alkenylated β-lactam derivatives and studied their metathetic behavior. Here, ring-opening metathesis is more favorable than ring-rearrangement metathesis. Molecular modelling studies revealed that the orientation of two olefinic moieties of β-lactam derivatives are far apart and therefore ring-rearrangement metathesis did not occur and ring-opening metathesis is only feasible.

Boiling diendo- or diexo-2-aminobicyclo[2.2.1]hept-5-ene-3- carbohydrazides 1 with 3-aroylnorbornenecarboxylic acid 2 in toluene yielded the pyrimido[1,2-b]pyridazine 4 directly in a double retro Diels-Alder process. Similarly, the reaction of anthranilic hydrazide 5 and 2 furnished the tricyclic benzo-fused analogue 7 via a single cycloreversion. The principle of the new method applied: the reactants were built up on cyclopentadienes and the dienes were cleaved by heating after condensation to furnish hetero bicyclic compound.
STEREOCHEMICAL STUDIES -- 79 SYNTHESIS AND KINETIC STUDY ON THE RETRODIENE DECOMPOSITION OF NORBORNENE-CONDENSED 1,3-OXAZIN-4-ONES

The cis-exo-amino acid 3 with norbornene skeleton was converted into 2-aryl-cis-exo-1,3-oxazin-4-ones 5a-d.These compounds, similarly to the diendo isomers 1a-d studied by us earlier, undergo retrodiene decomposition under mild conditions to give 2-aryl-6
