✦ Synopsis

A Concise Synthesis of Rigidified β-Amino Acids via Sulfanyl Radical Addition-Cyclization of Oxime Ethers and Hydrazones.

-Sulfanyl radical cyclization of alkenyl-tethered oxime ethers and hydrazones (I) provides cis/trans mixtures of the cyclized products (III) and (IV). The cyclopentylamines (IIIb)/(IVb) are useful precursors for the synthesis of the antifungal antibiotic cispentacin (V).
