- W2012893237 abstract "An alternative method for the synthesis of 2-amino-5,6-dihydro-4H-pyran-4-ones and 5,6-dihydro-4H-pyran-4-ones is described. This preparation makes use of the condensation of titanium enolates derived from β-hydroxy ketones with phosgene iminium chloride or trimethylorthoformate, respectively. The in situ formation of the necessary titanium complex from an aldol condensation using simple ketone and aldehyde precursors makes for a one-pot double condensation synthesis of the desired dihydropyrones." @default.
