amounts of cyclic byproducts of aldol addition with stoichiometry deviating from a regular 1:1 addition pattern were formed when the reaction of acetone with aromatic aldehydes was promoted by polymer-supported proline-incorporated catalysts. These adducts, unprecedented in the context of the aldol reaction, are most probably formed via a multistep domino mechanism.(© Wiley-VCH Verlag GmbH & Co. KGaA
当丙酮与芳香醛的反应由聚合物负载的脯氨酸掺入催化剂促进时,会形成大量羟醛加成的环状副产物,其化学计量偏离常规的 1:1 加成模式。这些在羟醛反应中前所未有的加合物很可能是通过多步多米诺机制形成的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
