Description |
The chiral vicinal diols prepared by asymmetric dihydroxylation in high enantioselectivities provide an excellent platform for separable diastereomers in the Johnson-Claisen rearrangement. The separated syn-diastereomers were converted into the advanced gamma-(lactone-lactol) intermediates (in six steps, 26-27% overall yields) for the synthesis of (-)-nor-canadensoiide, (-)-canadensolide and (-)-sporothriolide.
