An innovative and facile synthesis of the title compound has been developed starting from (R)-cyclohexylidene glyceraldehyde. The key step in the synthesis is a chiral template-driven Grignard addition with absolute diastereocontrol. The other attractive features are the operational simplicity and the use of inexpensive compounds/reagents.
