WitrynaEarly process development and salt selection for AMG 837, a novel GPR40 receptor agonist, is described. The synthetic route to AMG 837 involved the convergent synthesis and coupling of two key fragments, ( S )-3- (4-hydroxyphenyl)hex-4-ynoic acid ( 1) and 3- (bromomethyl)-4′- (trifluoromethyl)biphenyl ( 2 ). WitrynaA wide range of ADH/KRED enzymes now exist with both R and S selective enzymes available. There are now many examples of ADH/KRED enzymes being evolved to reduce more complex/hindered ketone substrates. Key to the success of a ADH/KRED reduction is driving the NAD (P)H cofactor recycle. This is normally done using a …
