Stereospecific synthesis of 9-demethylretinoids via palladium-catalyzed vinylboronic acid-vinyl iodide cross coupling
摘要:
A stereospecific synthesis of 9-demethylretinoids with either trans or 11-cis geometries, based on the thallium-accelerated palladium-catalyzed cross-coupling reactions of an (E)-1-alkenylboronic acid and (E) or (Z)-alkenyl iodides, is described.

A novel approach to the synthesis of retinoids and arotinoids (including heterocyclic analogs) is described which is based on the thallium-accelerated palladium-catalyzed cross-coupling of boronic acids with a variety of electrophiles (the Suzuki reaction).

coupling for the formation of the side-chain single bonds. On employing the experimental catalytic conditions developed by Farina [Pd2(dba)3, AsPh3, NMP] we have modified the electronic and steric requirement of the coupling parters, alkenyl stannanes and electrophiles (alkenyl iodides and triflates). The comprehensive survey afforded appropriately matched components for every bond formation considered.
