The catalytic generation of activated carboxylates from epoxyaldehydes enables the direct, stereoselective synthesis of beta-hydroxyesters under mild, convenient reaction conditions. In addition to providing a new method for the synthesis of anti-aldol adducts, this chemistry unveils a mechanistically viable solution to the catalytic, waste-free synthesis of esters.
ClickFerrophos families and tested for the Cu(I)-catalyzed asymmetric reductivealdolreaction of ketones and aldehydes with an acrylic ester in the presence of phenylsilane. The Cu(I)-ClickFerrophos complex is efficient for the reaction of ketones with methylacrylate to afford the erythro adducts both highlydiastereo- and enantioselectively; the diastereomeric ratio of erythrolthreo is improved when compared
