3-Butyn-2-one condenses with itself in the presence of 0.1 molar equiv of Dabco providing 80% yield of E-3-(1-buten-3-yn-2-oxy)-buten-2-one. Substitution at the acetylene terminus prevents the condensation. However, such ketones can be condensed with terminal acetylenic ketones to provide the cross
Rac 1,3-pentanediamine reacts with glyoxal to give a 1:1 mixture of diastereomers from which can be isolated (2R\*,2'S\*,4S\*,4'R\*)-4,4'-diethylperhydro-2,2'-bipyrimidine. Subsequent treatment with HCHO, MeCHO, EtCHO, and i-PrCHO gives cis and to a lesser extent trans fused 1:1 condensation product
