The stereocontrolled synthesis of (+)-tetrahydropseudodistomin (3) from D-serine features the use of the dibenzyltriazone group for amino protection and establishes the absolute stereochemistry of the naturally occurring calmodulin antagonists pseudodistomin A and B (1 and 2b, respectively).

An efficient asymmetric synthesis of (+)-tetrahydropseudodistomin is described. The important synthetic features include a Maruoka asymmetric allylation and a Sharpless asymmetric dihydroxylation as key steps for the generation of chirality at C-2, -4, and -5 of the trisubstituted piperidine ring.
