computations and totalsynthesis to assign the absolute configuration of a new natural product. The expected specific rotations of the (7S,10R)- and (7R,10R)-isomers of pitiamide A in a CHCl3 solvent continuum model were determined as +8 and −39, respectively, by CADPAC calculations of the electric-dipole−magnetic-dipole polarizability tensor. Total syntheses of these two stereoisomers of the marine metabolite
