Abstract
1,3,5-Trisubstituted 1,3,5-triazinanes (hexahydro-1,3,5-triazines), as stable and
readily available surrogates for formaldimines, have found extensive applications
for the construction of various nitrogen-containing compounds. The formaldimines,
formed in situ from this reagent class, can participate in various aminomethylation
and cycloaddition reactions. This short review presents recent advances in this field
with emphasis on the conceptual ideas behind the developed methodologies and the reaction
mechanisms.
