Palladium-catalyzed dehydration of primary amides to nitriles efficiently proceeds under mild, aqueous conditions via the use of dichloroacetonitrile as a water acceptor. A key to the design of this transfer dehydration catalysis is the identification of an efficient water acceptor, dichloroacetonitrile, that preferentially reacts with amides over other polar functional groups with the aid of the Pd catalyst and makes the desired scheme exergonic, thereby driving the dehydration.

Sphingosine 1-phosphate (S1P), a potent phospholipid growth and trophic factor, is synthesized in vivo by two sphingosine kinases. Thus these kinases have been proposed as important drug targets for treatment of hyperproliferative diseases and inflammation. We report here a new class of amidine-based sphingosine analogues that are competitive inhibitors of sphingosine kinases exhibiting varying degrees of enzyme selectivity. These inhibitors display KI values in the submicromolar range for both sphingosine kinases and, in cultured vascular smooth muscle cells, decrease S1P levels and initiate growth arrest.

(Chemical Equation Presented) A general strategy for the amino acid homologation via Blaise reaction and subsequent reduction is presented. This strategy involves the preparation of protected α-amino nitriles from the corresponding amino acids, followed by the zinc-mediated condensation of tert-butyl bromoacetate, to give the imidazolidones after iminozincate cyclization. Reduction gave the saturated imidazolidinones with cis or trans stereochemistry, depending on the reduction conditions. This strategy was applied to nonfunctionalized amino acids and to functionalized amino acids such as serine and aspartic acid. Additionally, acidic hydrolysis of cis or trans imidazolidinones to the corresponding chiral 4-aminopyrrolidones is described.
