Dihalides X-(Z)-X, [Z = (CH2)n; n = 1-7 or CH 2CH=CHCH2] react with the phenol group of vanillyl alcohol to give the dialkylated derivatives HOCH2-Ar-O-(Z)-O-Ar-CH 2OH (2), which in turn, in the presence of formic acid, afford the corresponding D3 cryptophanes (3), with, in some cases, minor amounts of the C3h isomers (4).
