The first efficient and general nickel-catalyzed hydrocyanation of terminal alkynes with Zn(CN)2 in the presence of water has been developed. The reaction provides a regioselective protocol for the synthesis of functionalized vinyl nitriles with a range of structural diversity under mild reaction conditions while obviating use of the volatile and hazardous reagent of HCN. Deuterium-labeling experiments confirmed the role of water as the hydrogen source in this hydrocyanation reaction.

Novel azido- and amino-functionalised fluorescent probes based on the BODIPY framework have been developed. The probes can be easily and cheaply synthesised, exhibit the highly desirable BODIPY fluorescent properties, and are amenable to 'click' and pepti
Studies toward the total synthesis of eletefine: An efficient construction of the AB ring system
Cody, Jeremy A.,Ahmed, Ijaz,Tusch, Douglas J.
supporting information; experimental part, p. 5585 - 5587 (2010/10/19)
Synthetic studies toward eletefine, a novel stephaoxocane alkaloid, were undertaken in an attempt to provide a general methodology to aid in the synthesis of other novel stephaoxocanes. An efficient construction of the AB ring system with increased functionality is described which presents a flexible approach to synthesizing the C and D rings of eletefine.
A large scale and concise synthesis of γ-linolenic acid from 4- chlorobut-2-yn-1-ol
Durand, Sandrine,Parrain, Jean-Luc,Santelli, Maurice
, p. 1015 - 1018 (2007/10/03)
A large scale and concise synthesis of γ-linolenic acid is described. The key step of the synthesis involves a copper salt mediated cross-coupling of two different alkynes and chlorobutynol.
The total synthesis of 20-hydroxyhepoxilins A3, new metabolites of the hepoxilin family of eicosanoids

An enantiodirected total synthesis of 20-hydroxyhepoxilins A3, new eicosanoids of the lipoxygenase metabolism of arachidonic acid, was perfomed. The synthetic samples were found to be identical to the major metabolite formed upon incubation of (85)-hepoxilin A3 with human neutrophiles, which demonstrated that it has the structure of (8S)-20-hydroxy-HxA3.
Indirect electroreductive sequential radical reaction catalyzed by a Ni(II) complex. One-step preparation of functionalized (methylene)cyclopentanes
Ozaki,Mitoh,Ohmori
, p. 1435 - 1440 (2007/10/03)
Substituted (methylene)cyclopentanes were prepared by one-step reaction at room temperature from butynyl iodides and activated olefins by sequencing of free radical addition and cyclization reactions. The reactions, which were conducted by indirect electroreduction catalyzed by a nickel(II) complex, proceeded with modest selectivity for formation of the Z(methylene)cyclopentanes.

The synthesis of many saturated, acetylenic, olefinic (Z or E) fatty acids labeled with 123I or 131I at the ω-position has been achieved.The radioactive iodine atom is introduced by a I-, *I- exchange reaction; the influence on the yield of several parameters - presence of iodine carrier, fatty acid and water concentrations, solution acidity - has been studied.Experimental conditions which produce labeling yields higher than 95percent have been defined; these results have lead to a very easy labeling method used in several hospitals in the external study of myocardial metabolism of fatty acids.
