ChemInform Abstract: anti‐Diastereo‐ and Enantioselective Carbonyl (Hydroxymethyl)allylation from the Alcohol or Aldehyde Oxidation Level: Allyl Carbonates as Allylmetal Surrogates.

Abstract

The first enantioselective carbonyl (hydroxymethyl)allylation in the presence of aromatic, allylic, or aliphatic alcohols (II) is reported employing an (S)‐SEGPHOS‐modified iridium C,O‐benzoate complex to provide products (III) in good isolated yields, good anti‐diastereoselectivities and high enantioselectivities.

Advancement of vinylene carbonate as a coupling partner in metal-catalyzed C–H functionalization

“…In addition, other functionalized cyclic organic carbonates have also evolved into diversified appealing coupling partners in modern organic synthesis. [10][11][12][13] Generally, these five or six-membered saturated cyclic organic carbonates generate interesting zwitterionic intermediates upon decarboxylation under transition-metal (TM) catalysis, [14][15][16][17] and the remaining fragments further react with electrophiles or nucleophiles to delivery linear or cyclic products (Fig. 1).…”
