Vitamin A (all-trans-retinol, 1, Figure 1) is considered the most multifunctional vitamin in the
human body. 1 It plays key roles in many physiological processes such as vision …

A formal total synthesis of oximidine II has been achieved, employing a Suzuki-type coupling
approach to construct the highly strained, polyunsaturated 12-membered macrolactone. To …

Arylboronic acids react with alkenes in acetic acid at 25° C in the presence of a catalytic
amount of palladium (II) acetate together with sodium acetate to give the corresponding aryl …

The palladium-catalyzed cross-coupling reaction of cyclopropylboronic acids with acyl
chlorides was achieved by the combination of Ag2O and K2CO3 as the base. Highly …

Organochromium compounds can be prepared by two methods:(1) transmetallation from the
corresponding organolithium,‐magnesium, or–zinc compounds with chromium (III) halides …

Potassium pentafluorophenyl-and trifluorovinyltrifluoroborates, both containing electron-
