Heterocyclic Nucleoside Analogues by Cycloaddition Reactions of 1-Vinylthymine with 1,3-Dipoles. -The scope of the 1,3-dipolar cycloaddition reaction of nitrile oxides, nitronates and azides with 1-vinylthymine (I) is studied. Highly reactive 1,3-dipoles give the corresponding cycloadducts such as
## A&&KB& -The nitrile N-oxide 4 undergoes a reversible cycloaddition to the carbonyl group of the l-oxa-3-azoniabutatriene salts 3a-c to give the geminal dioxy substituted 2-azoniaallene salts Sa-c. Azibenzil 7 and 3a,d afford the 2-azoniaallene salts 8a,d. With the nitrone 11 the cumulene 36 rea
