An enantiodivergent asymmetric cyclization of N-Boc-N-ω-bromoalkyl-α-amino acid derivatives has been developed. With potassium amide bases in DMF, cyclization proceeds with retention of configuration, while inversion of configuration was observed with lit
Simple access to novel azetidine-containing conformationally restricted amino acids by chemoselective reduction of β-lactams

Reduction with diphenylsilane and catalytic amounts of tris(triphenylphosphine)rhodium(I) carbonyl hydride resulted in an efficient, chemoselective method for the transformation of amino-acid-derived β-lactams into the corresponding azetidines, which afte
