Synthetic studies toward Phorboxazole A. Stereoselective synthesis of the C3-C19 and C20-C32 subunits

A stereocontrolled synthesis of two fragments comprising the macrocyclic core of Phorboxazole A is described. The C3-C19 bis-pyran segment is prepared utilizing reiterative enantioselective allylations from homochiral allylstannanes followed by stereoselective cyclizations. The pentasubstituted tetrahydropyran of the C20-C32 fragment is prepared via an intramolecular stereoselective cationic cyclization of a methoxymethyl ether derivative.
