describe the synthesis and biological activity of HIV-1 PR inhibitors based on four novel dihydroxyethylene isosteres of the Phe-Pro and Pro-Pro dipeptides. The isosteres, containing four stereogenic centers, were synthesized in high yield and excellent stereoselectivity via the cyclization of epoxy amines derived from α-amino acids. The inhibitors were assembled by coupling the isosteres with suitable

on amino acid and β-ketophosphonate chemistry, as well as employment of internal asymmetric induction for the creation of the new chiral centers proved successful. With proper choice of reaction conditions, the approach can also be applied in selective preparation of several isomers of deoxycastanospermine. The length (9 steps) and overall yield of the title compound trihydroxyindolidine 1, 7.3%, compares
