Total syntheses of (+)-valiolamine (1) and (-)-1-epi-valiolamine (2) from the naturally abundant (-)-shikimic acid are described. Ethyl 3-epi-5-O-methylsulfonyl-shikimate (3), as the key common intermediate, was first synthesized in five steps in 74 % overall yield, and then converted into the targets 1 and 2 in seven steps in 48 and 41 % overall yield, respectively.
