AN EXPEDIENT STEREOCONTROLLED SYNTHESIS OF 7-CIS-RETINOIDS
摘要:
Ethyl (7Z)-retinoate 5 has been efficiently synthesized using as key step the Suzuki coupling of an in situ generated alkenylboronic acid and the geometrically homogeneous tetraenyliodide with (Z)-geometry, itself obtained by yodomethylenation according to Stork's conditions. Functional group manipulation then afforded (7Z)-retinal 7.
