Selective Oxidation of 25,27-Bis- (3-formylphenoxylethoxy)-p-tert-butylcalix[4]arene
نویسندگان
چکیده
Reaction of 25,27-bis-(3-formylphenoxyethoxy)-p-tert-butylcalix[4]arene (1) with 20% mole of KCN in ethanol and i-propanol yielded monoethylester (2) (50%) and monoisopropylester (3) (15%). Compound 1 was not oxidized by air in the absence of KCN under reflux. The Cannizzaro reaction of 1 in ethanol using KOH gave bis-alcohol (4), acid-alcohol (5).

The selective monoalkylation at the smaller (lower) rim of the p-tert-butylcalix[4]- and -[6]arenes using bis(butyltin)oxide and different alkylating agents is described. The procedure is remarkable for the mild conditions used allowing an efficiently access to monoalkylated calixarene derivatives in moderate to good yields. Monoalkynylcalix[4]arene and monoalkynylcalix[6]arene have been synthe...
