A concise total synthesis of enantiopure (+)-preussin (1) from L-phenylalanine (3) is described. The key steps involve i) syn-selective formation of the 1, 2-amino alcohol fragment2, via chelation controlled addition of allylmagnesium bromide toN-Boc-phenylalaninal, and ii) L-selectride® mediated stereoselective reduction of the ketone8 to the alcohol derivative9 with the required stereochemistry for
