An efficient synthesis of a potential (-)-reserpine intermediate from (-)-shikimic acid of the chiral pool

A highly stereoselective route to the polysubstituted chiral octahydrobenzofuran 12, a potential synthon for the E-ring core in the (-)-reserpine synthesis, is described. The α-bromo acetal 11 was obtained from inexpensive (-)-shikimic acid (3) through a series of highly stereoselective chemical reactions (Scheme). Et3B/Bu 3SnH-Mediated intramolecular radical cyclization of 11 led to compound 12 with the required configuration.

Total synthesis of (-)-reserpine using the chiron approach

A highly stereocontrolled synthesis of ring D/E precursor to reserpine has been developed starting from (-)-quinic acid as a chiral template. The total synthesis of (-)-reserpine is described through the cyclization of an immonium lactam intermediate.
