TiO2-supported goldnanoparticlecatalyst was found to allow the N-formylation of various amines, including normally unreactive anilines, using CO2 as the carbonyl source under a H2 atmosphere. A series of reducible functional groups, such as olefins, halogens, carbonyls, carbamates and cyano moieties, were completely retained during the formylation, demonstrating the highly selective formylation of
advantages of our methodology include an increased synthesis speed, very mild conditions giving access to hitherto unknown or highly reactive classes of isocyanides, rapid access to large numbers of functionalized isocyanides, increased yields, high purity, proven scalability over 5 orders of magnitude, increased safety and less reaction waste resulting in a highly reduced environmental footprint. For example
This invention is directed to oxoazaheterocycyl compounds which inhibit Factor Xa, to oxoazaheterocycyl compounds which inhibit both Factor Xa and Factor IIa, to pharmaceutical compositions comprising these compounds, to intermediates useful for preparing these compounds, to a method of directly inhibiting Factor Xa and to a method of simultaneously directly inhibiting Factor Xa and Factor IIa..

The firstsyntheticroute to yndiamides, a novel class of double aza‐substituted alkyne, has been established by the copper(I)‐catalyzed cross‐coupling of 1,1‐dibromoenamides with nitrogen nucleophiles. The utility of these compounds is demonstrated in a range of transition‐metal‐catalyzed and acid‐catalyzed transformations to afford a wide variety of 1,2‐diamide functionalized products.
