    • Baldwin reported the strong directing effect of the Boc-(S)-serine residue on the selective formation of the 65 bridgehead configuration in his tandem ozonolysis-cyclization of Boc-(S)-Ser-(S/R, homoallyl)Gly- OBn substrates, which gave the corresponding (6S)-1-aza-5-oxobicyclo-[4. 3.0] product in 72-77% yield with high diastereoselectivity (6S:6R, > 7:1) regardless of the absolute configuration of the homoallylglycine residue (see ref 22, Marshall also reported a similar directing effect of Boc-(S)-homoserine residue in his electrochemical (i.e, anodic electrolysis) cyclization of Boc-(S)-homo-Ser-(S/R)-Pro-OMe, which gave (7S)-1-aza-6-oxabicyclo[5.3.0] product exclusively, regardless of the absolute configuration of the proline residue although the chemical yields were only moderate 48-52, see ref 26
