1,3,5-Substituted 2,4,6-triethylbenzene derivatives bearing pyridine/pyrimidine and purine units were synthesized and their potential to function as carbohydrate receptors was evaluated. Compounds consisting of 2-chloro-9H(7H)-purin-6-yl unit (e.g., I) have the ability to act both as carbohydrate-binding agents and as a basis for further functionalization through the nucleophilic displacement of the chlorine atom. Microwave-assisted reactions and/or the application of sealed tubes allowed the preparation of derivatives with a varying substituent pattern on the purine ring. The relatively drastic reaction conditions required for the successful functionalization reflect the unfavorable influence of the bulky C6-substituent on the nucleophilic substitution at purine C2. Initial binding studies towards carbohydrates showed that the properties of this type of purine-bearing compounds can be fine-tuned by the variation of the C2-substituent of the purine ring and represents a valuable basis for the identification of new structure-activity relationships. Such findings are of high importance for further developments in the area of mol. recognition of carbohydrates by artificial receptors.
