Phosphorus pentoxide is commonly used for the dehydration of heterocyclic carboxamides to the corresponding nitriles. In this report, the use of cyanuric chloride/N,N-disubstituted formamide for this reaction is described. The advantages of this proc

In this contribution, the first examples of the catalytic highly enantioselective reduction of cyclic meso-anhydrides to lactones and of thioanhydrides to thiolactones are described. The N-benzyl protected key building blocks in the industrial synthe

3-(Bromoethynyl)azetidine is a highly energetic building block (decomposition energy up to −1800 J g–1) that was required in multikilogram quantities for the production of an API. The development of a four-step, fully telescoped, scalable sequenc

Pyrimidine synthesis starting from acrylonitrile has been known since the 1960s. The new Lewis acid-catalyzed condensation reaction allows the synthesis of 4-aminopyrimidines starting from the easily accessible chemical acrylonitrile without the need

Chiral pyridyl alcohols have been prepared by developing a two-step approach that uses the asymmetric cyanation of aldehydes- to give cyanohydrins and subsequent [2+2+2]-cyclotri-merization reaction with acetylene.

In this account, scope and limitations for the application of hydrolytic enzymes (lipases) to large-scale syntheses of economically important bulk products (vitamins) are discussed. In three case studies, biocatalytic alternatives were compared to
