Nagayama, Satoshi,Kobayashi, Shu
, p. 685 - 686 (1998)
In the presence of a catalytic amount of lanthanide triflate (Ln(OTf)3), imines reacted with ethyl diazoester in hexane at room temperature to afford the corresponding aziridines in high yields with high diastereoselectivities. Based on these r

Starting from simple anilines and ester arylpropiolates, an efficient one-pot synthesis of 2-arylindole-3-carboxylate derivatives has been developed through copper-mediated sequential hydroamination and cross-dehydrogenative coupling (CDC) reaction. The i

The results of a study of the reactivities of alkynyl Fischer carbenes in the syntheses of diazaborinine derivatives 7a-i are reported. The strategy employed included the use of β-amino-α,β-unsaturated carbenes (3a–j) with different amines in order to determine the scope of a previously unknown catalytic reaction in the presence of copper salts and anilines. The reaction was highly stereoselective, yielding (Z)-isomers of the β-amino-1-azadiene framework as the main products (4a–o). As an extension of this research, the compounds 4a–o proved to be suitable precursors for the syntheses of diazaborinine scaffolds in good yields (7a-i).
