Ye, Fei published the artcileSolvent-free ruthenium trichloride-mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and cyanamides: a convenient access to 2-aminopyridines, Safety of N,N-Dibenzylcyanamide, the publication is Organic Chemistry Frontiers (2017), 4(6), 1063-1068, database is CAplus.
A convenient access to functionalized 2-aminopyridines via a solventless Ru-catalyzed [2 + 2 + 2] cycloaddition reaction of α,ω-diynes and cyanamides was described. This transformation efficiently proceeded in the presence of a stable, easy to handle, and cost-effective RuCl3·nH2O complex, leading to various 2-aminopyridines in good to excellent yields according to an eco-friendly, straightforward approach.
Organic Chemistry Frontiers published new progress about 2451-91-4. 2451-91-4 belongs to amides-buliding-blocks, auxiliary class Nitrile,Amine,Benzene, name is N,N-Dibenzylcyanamide, and the molecular formula is C16H24BF4Ir, Safety of N,N-Dibenzylcyanamide.
