Syntheses, transformations and applications of aminonaphthol derivatives prepared via modified Mannich reactions [PDF]
, 2013 A special alteration is the three-component modi fi ed Mannich reaction (mMR), in which formaldehyde is replaced by an aromatic aldehyde, the secondary amine by ammonia, and the C e H acid by an electron-rich aromatic compound such as 1- or 2 ...

Experimental and Theoretical Evidence for Nitrogen-Fluorine Halogen Bonding in Silver-Initiated Radical Fluorinations [PDF]
, 2019 We report experimental and computational evidence for nitrogen–fluorine halogen bonding in Ag(I)-initiated radical C–H fluorinations. Simple pyridines form [N–F–N]+ halogen bonds with Selectfluor to facilitate single-electron reduction by catalytic Ag ...

Beilstein Journal of Organic Chemistry, 2019 A series of novel 3-methylphosphonylated [1,2,4]triazolo[4,3-a]pyridines was accessed through a 5-exo-dig-type cyclization of chloroethynylphosphonates and commercially available N-unsubstituted 2-hydrazinylpyridines. In addition, 3-methylphosphonylated [

Synthetic strategies for 5- and 6-membered ring azaheterocycles facilitated by iminyl radicals [PDF]
, 2016 The author thanks EaStCHEM for financial support.The totality of chemical space is so immense that only a small fraction can ever be explored. Computational searching has indicated that bioactivity is associated with a comparatively small number of ring ...
