摘要
Under the assistance of beta-cyclodextrin, purine was effectively alkylated at N9 together with up to 99% conversion and good to excellent yield using water as the solvent. High regioselectivity-N9/N7 selectivity>99:1 was attributed to the beta-cyclodextrin cavity blocked the N7 of purines ring. (c) 2012 Elsevier Ltd. All rights reserved.
