A method of providing a desirable vanilla beany flavor in an orally-receivable product, includes adding to a product base at least one of divanillyl succinate or at least one compound according to Formula I or Formula II
in which R′ is selected from the group consisting of hydrogen, methyl and —CHO, and R is selected from the group consisting of hydrogen. C1-C10 linear alkyl. C3-C10 branched alkyl, C2-C10 linear alkenyl, C3-C10 branched alkenyl, C1-C10 hydroxyalkyl, C2-C10 carboxyalkyl, and tetrahydrofuranyl.
process has been developed for the iridium(I)‐catalyzed vinylic C−H borylation of α,β‐unsaturated esters with bis(pinacolato)diboron (B2pin2). These reactions proceeded in octane at temperatures in the range of 80–120 °C to afford the corresponding alkenylboronic compounds in high yields with excellent regio‐ and stereoselectivities. The presence of an aryl ester led to significant improvements in the
