A short and efficient total synthesis of isoroquefortine C, the 3,12-(Z)-isomer of roquefortine C, from L-tryptophan methyl ester hydrochloride and 4(5)-(hydroxy)methylimidazole hydrochloride is described.
A concise synthesis of anserine and related compounds was accomplished by Et-DuPhos-Rh-catalyzed asymmetric hydrogenation of dehydrohistidine derivatives in 2,2,2-trifluoroethanol, which played a key role in improving the yield and selectivity.
