  Asymmetric Morita–Baylis–Hillman reaction catalyzed by pepsin

  摘要：

  Pepsin from porcine gastric mucous shown catalytic promiscuity was first discovered to catalyze the Morita-Baylis-Hillman (MBH) reaction between aromatic aldehydes with 2-cyclohexen-1-one or 2-cyclopenten-i-one in a two-phase medium of phosphate buffer/cyclohexane in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO). The best results of the corresponding MBH products up to 77% yield and 38% ee were achieved. (C) 2015 Elsevier B.V. All rights reserved.

  Novel bis(thio)urea organocatalysts were synthesized from axially chiral (R)-(-)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthyl-2,2'-diamine (H-8-BINAM), and their catalytic abilities have been examined in the Morita-Baylis-Hillman reaction of 2-cyclohexen-1-one or 2-cyclopenten-1-one with a wide range of aromatic aldehydes in combination with DABCO. The best result was achieved in the reaction of 3-fluorobenzaldehyde with 2-cyclohexen-1-one to give the desired Morita-Baylis-Hillman product in 79% yield and 88% ee.
