Chemical synthesis study demonstrates a concise enantioselective route to phthioceranic acid in eight linear steps, highlighting an efficient strategy for constructing complex bacterial cell-wall...
A new strategy for highly concise, convergent, and enantioselective access to polydeoxypropionates has been developed. ZACA‐Pd‐catalyzed vinylation was used to prepare smaller deoxypropionate fragments, and then two key sequential Cu‐catalyzed stereocontrolled sp3–sp3 cross‐coupling reactions allowed convergent assembly of smaller building blocks to build‐up long polydeoxypropionate chains with excellent stereoselectivity. We employed this strategy for the synthesis of phthioceranic acid, a key constituent of the cell‐wall lipid of Mycobacterium tuberculosis, in just 8 longest linear steps with full stereocontrol.
