Cross silyl benzoin additions catalyzed by lanthanum tricyanide
Bausch, Cory C.,Johnson, Jeffrey S.
, p. 4283 - 4285 (2004)
From a screen of (cyanide)metal complexes, an improved catalyst for the cross silyl benzoin addition was discovered. Several M(CN)3 complexes (M = Ce, Er, Sm, Y, Yb, La) were evaluated and lanthanum tricyanide was identified as the optimal cata
De Novo Synthesis of α-Hydroxy Ketones by Gallic Acid-Promoted Aerobic Coupling of Terminal Alkynes with Diazonium Salts

An unprecedented metal-free direct preparation of unprotected α-hydroxy ketones from terminal alkynes under mild conditions with diazonium salts as the arene source and without the requirement of irradiation is described. The process is general and fully compatible with a wide variety of substitution in both reactants. Experimental and computational evidence strongly suggest the involvement of radical species in the transformation.

A series of 4,5-diaryl-1H-imidazole-2(3H)-thione was synthesized and their inhibitory potency against soybean 15-lipoxygenase and free radical scavenging activities were determined. Compound 11 showed the best IC50 for 15-LOX inhibition (IC50 = 4.7 μM) and free radical scavenging activity (IC50 = 14 μM). Methylation of SH at C2 position of imidazole has dramatically decreased the 15-LOX inhibition and radical scavenging activity as it can be observed in the inactive compound 14 (IC50 >250 μM). Structure activity similarity (SAS) showed that the most important chemical modification in this series was methylation of SH group and Docking studies revealed a proper orientation for SH group towards Fe core of the 15-LOX active site. Therefore it was concluded that iron chelating could be a possible mechanism for enzyme inhibition in this series of compounds.
