✦ Synopsis

Tributyltin Hydride-Mediated Free-Radical Cyclization of Allene-Tethered Oxime Ethers and Hydrazones.

-It offers a convenient method to prepare (vinylstannyl) cyclopentylamine derivatives. The sitedirected intermolecular attack of the tributyltin radical at the allene moiety and the final size of the ring after cycloisomerization is found to depend on the substitution pattern. Treatment of the products with HCl gives the corresponding destannylated derivatives in good yields. -(MARCO-CONTELLES, J.;
