Novel direct CâH borylations of 7-deazapurines to position 8 by B2pin2 under Ir catalysis were followed by Suzuki cross-couplings with aryl halides and other functional group transformations to give diverse 8-substituted 7-deazaadenines.
新型直接C–H硼化反应能够在铱催化下将B2pin2应用于7-脱氮嘌呤的8位,随后通过与芳基卤化物的铃木交叉耦合及其他功能团转化,得到多样化的8取代7-脱氮腺嘌呤。
