Chemical Development of MDL 103371:  An N-Methyl-d-Aspartate-Type Glycine Receptor Antagonist for the Treatment of Stroke

Abstract: MDL 103371 is a N-methyl-D-aspartate (NMDA)-type glycine receptor antagonist for the potential treatment of stroke. Evaluation of five different synthetic routes, which included Stille, Suzuki, enol ether, Knoevenagel, and the Mukaiyama coupling reactions, revealed the Knoevenagel approach superior for preparing large quantities of drug substance for evaluation. The overall process utilized some classical chemistry. Fischer indole cyclization, followed by a Vilsmeier-Haack formylation and a Knoevenagel condens… Show more

“…Optimized yields and selectivities for a variety of “real world” substrates in the presence of several other functional groups can be very high, but it has to be stressed that this is not always the case 54. An interesting result was reported for the hydrogenation of a complex nitroarene intermediate with a cyanovinyl moiety whereby a Rh/Al 2 O 3 catalyst in the presence of NEt 3 achieved excellent results 56…”
