methodology is compatible with a wide-range of aliphatic linear, branched, and ester functionalized N-substituents. Unexpectedly, the formation of regioisomers featuring a 1,2,3-contiguous substitution pattern in the aromatic ring of the indene core was observed. Three distinct combinatorial libraries with a total of 111 of members were synthesized, and 80 highly substituted dihydroindenoisoquinolines structurally
This contribution described the first iron-catalyzed chemoselective reduction of secondary carboxamides to aldimines under hydrosilylation conditions. The reaction is catalyzed by the well defined Fe(CO)4(IMes) complex, in the presence of 2.5 equiv. of diphenylsilane under UV irradiation (350 nm) at room temperature.
