A highly stereocontrolled and flexible access to biologically relevant polydeoxypropionates in optically pure form has been developed. Taking advantage of our previously established strategy for the asymmetric and stereo-divergent synthesis of trideoxypropionate building blocks, we have now been able to assemble large polydeoxypropio-nate chains with defined configuration in a highly convergent manner. Central steps of this approach include two Suzuki-Miyaura cross-coupling reactions with subsequent highly diastereoselective hydrogenations to join three advanced synthetic intermediates in excellent yield and with full stereochemical control. We have applied this strategy successfully towards the asymmetric synthesis of glycolipid membrane components phthioceranic acid and hydroxyphthioceranic acid, the latter of which was synthesized on a half-gram scale.

Simply convergent: The polydeoxypropionates 1 and 2 are important constituents of the cell wall of Mycobacterium tuberculosis. Key steps in their total synthesis include two Suzuki-Miyaura cross-coupling reactions and two highly diastereoselective iridium-catalyzed hydrogenations. The trideoxypropionates employed as central building blocks were prepared by sequential oxy-Cope rearrangement, hydrogenation, and enolate methylation. Copyright
