Synthesis of unit-B of cryptophycin-24 via Sharpless asymmetric dihydroxylation
A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of alpha-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of alpha-amino acid without the loss of chirality during the transformation.
