There is provided a process for the manufacture of 2-alkoxymethylacrolein compounds via the reaction of an appropriate alcohol and acrolein in the presence of an acid and a trisubstituted amine to form an intermediate and the subsequent reaction of the intermediate with formaldehyde in the presence of an acid and a disubstituted amine. There is also provided a process for the manufacture of 3-alkoxymethylquinolines from 2-alkoxymethylacrolein.

A de novo synthesis of substituted pyridines is described that proceeds through nucleophilic addition of a dithiane anion to an α,β-unsaturated carbonyl followed by metallacycle-mediated union of the resulting allylicalcohol with preformed trimethylsilane-imines (generated in situ by the low-temperature reaction of lithium hexamethyldisilazide with an aldehyde) and Ag(I)- or Hg(II)-mediated ring closure
