The substrate-controlled diastereoselective arylation of chiral aldehydes readily
available from carbohydrates is described, using the boron–zinc exchange reaction
to generate the transferable aryl groups. The methodology developed was applied to
the total synthesis of the styryllactone (+)-7-epi-goniofufurone and analogues thereof.
Key words
arylzinc reagents - boron–zinc exchange - diastereoselective addition - chelation
control - styryllactones
