متن کامل1,3-Dipolar Cycloaddition Reaction of Dibenzalaceton with Non-stabilized Azomethinylides: Synthesis of New Spirooxindolo(pyrrolizidines/ pyrrolidines)
1,3-dipolar cycloaddition reaction of 1 mol or 2 mol of dibenzalaceton with 1 mol of non-stabilized azomethinylides generated in situ by decarboxylative condensation of isatin and proline or sarcosine give the novel new spiro-oxindolo(pyrrolizidines/ pyrrolidines) instead of bis-spirooxindolo( pyrrolizidines/ pyrrolidines).

متن کاملA homo [3+2] dipolar cycloaddition: the reaction of nitrones with cyclopropanes.
Cycloadditions are among the most trusted of chemical transformations available to the synthetic chemist. The predictability of the transition state based on steric and electronic considerations allows for the strategic construction of complex molecular assemblies. While the Diels–Alder reaction has received the most attention, 1,3-dipolar cycloadditions have also maintained a place of prominen...
متن کاملRapid assembly of heterocycle grafted macrocycles via tandem one-pot double 1,3-dipolar cycloaddition reaction.
Synthesis of triazole linked macrocycles grafted with glycospiroheterocycle was accomplished by stereo- and regioselective tandem double 1,3-dipolar cycloaddition (1,3-DC) reaction. By this method we could construct complex chiral macrocycles in good yields from the easily available starting materials and we could achieve the synthesis of two heterocyclic rings involving simultaneous formation ...
