A new efficient approach for the synthesis of functionalized dihydro-pyrimido[4,3-d]coumarins is described. Use of benzyl- or tert-butyl acetoacetate and various salicyl aldehydes in typical Biginelli multicomponent reactions provides esters that can

The synthesis of some new [4.4]cyclophane diketals, monoketones, and diketones in good yields is reported along with the unusually low reactivity towards hydrolysis of the spiro-1,3-dioxane rings connected to the cyclophane bridges. The structural an

New molecular rotors, [7.7](2,6)pyridinocyclophanes (monomers and dimers) embedding 1,3-dioxanes in the bridges, were investigated by variable-temperature NMR, molecular modeling, and single-crystal X-ray diffractometry. The nitrogen-inside rotation
