, p. 1682 - 1683 (2002)
The one-pot three-component condensation of a β-ketoester, ammonia and an alkynone in the presence of a Bronsted or Lewis acid or Amberlyst 15 ion exchange resin provided 2,3,6-trisubstituted or 2,3,4,6-tetrasubstituted pyridines directly in good yield and with total regiocontrol.
Synthesis of pyridines and pyrido[2,3-d]pyrimidines by the Lewis acid catalysed Bohlmann-Rahtz heteroannulation reaction

, p. 1523 - 1526 (2001)
Lewis acids catalyse the Bohlmann-Rahtz heteroannulation reaction to generate highly functionalised pyridines from enamino esters and alkynones in a single synthetic step. Of the catalysts studied, ytterbium(III) trifluoromethanesulfonate and zinc(II) bromide are the two most efficient for the synthesis of pyridines and pyrido[2,3-d]pyrimidines, from ethyl β-aminocrotonate or 2,6-di-aminopyrimidin-4-one respectively, in up to 94% yield.
Bohlmann-Rahtz cyclodehydration of aminodienones to pyridines using N-iodosuccinimide
Bagley, Mark C.,Glover, Christian
experimental part, p. 3211 - 3227 (2010/09/04)
Cyclodehydration of Bohlmann-Rahtz aminodienone intermediates using N-iodosuccinimide as a Lewis acid proceeds at low temperature under very mild conditions to give the corresponding 2, 3,6-trisubstituted pyridines in high yield and with total regiocontrol.

Page/Page column 8, (2010/02/11)
The present invention relates to novel α-substituted arylalkylphosphonate derivatives and their uses for lowering plasma levels of apo (a), Lp(a), apo B, apo B associated lipoproteins (low density lipoproteins and very low density lipoproteins) and for lo
