Asymmetric dihydroxylation of heteroaromatic acrylates

N- and O-Heteroaromatic acrylates were dihydroxylated with high ees and good yields. While the AD of pyridyl and pyrryl acrylates afforded diverse yields under the present reaction condition, some corresponding N-substituted pyridyl and pyrryl acrylates (1d, 1e, 1g) proved to be appropriate substrates. The diols obtained can be used as chiral building blocks for the synthesis of various biologically active molecules.
