Complete autoassembly of dilactones 4-6 from dihydroxytetraesters of the type X2YC(CH2)nCYX2 (X = CO2R, Y=OH, n = 2,3) was performed in high yields under the conditions of acid or base catalysis.The classic syntheses of the Troeger's base, Meerwein ester, and dilactams were considered from the viewpoint of bicycle autoassembly. - Key words: α,ω-alkylene-bis-tartronates; autoassembly of dilactones of α,α'-dihydroxy-α,α'-dialkoxycarbonyladipic and -pimelic acids; acidic and base catalysis; NMR, IR, and mass spectra.
