A Silicon Tether Approach for Addition of Functionalized Radicals to Chiral α-Hydroxyhydrazones: Diastereoselective Additions of Hydroxymethyl and Vinyl Synthons

Stereocontrolled additions of hydroxymethyl and vinyl groups to chiral α-hydroxyhydrazones can be achieved by radical cyclizations using bromomethyl or vinyl radical precursors tethered via a temporary silicon connection. Tin-mediated 5-exo radical cycliz

Diastereoselective vinyl addition to chiral hydrazones via tandem thiyl radical addition and silicon-tethered cyclization

(equation presented) A diastereoselective method for addition of a vinyl group to α-hydroxy hydrazones under neutral tin-free radical cyclization conditions, leading to substituted vinylglycinols, is presented. Tandem thiyl radical addition/cyclization up
