Abstract: | Two efficient asymmetric syntheses of (2S,3S)-safingol have been developed starting from easily available (R)-cyclohexylideneglyceraldehyde. The key steps in the syntheses were a diastereoselective addition of a suitable alkylmagnesium or lithium reagent, and simple organic transformations. Compared to earlier syntheses, the route involving alkyllithium addition is more viable practically due to its excellent diastereoselectivity, use of inexpensive materials/reagents and operational simplicity. |
