microwave‐irradiated alcohol‐protecting strategy based on goldcatalysis utilizing benzyl alcohol, tert‐butyl alcohol and triphenylmethanol as alkylating reagents has been developed. This protecting strategy has wide functional group tolerance with satisfactory yields for the majority of the selected alcohols. The mechanism of this transformation was probed with oxygen‐18 isotope labelled alcohols assisted by

describe novel scaffold designs for nonpeptidic α-helixmimetics. The tricyclic scaffolds contain triazoles and reproduce amino acid side chains i, i+3, and i+7. The three different scaffolds are synthetically readily accessible, allow the introduction of further substituents to increase the versatility,and are suitable for library design. A modular synthesis route using Cu I- and Ru II-catalyzed azide–alkyne
我们描述了非肽类 α-螺旋模拟物的新型支架设计。三环支架含有三唑并复制氨基酸侧链 i、i+3 和 i+7。三种不同的支架在合成上很容易获得,允许引入更多的取代基以增加多功能性,并且适用于文库设计。开发了使用 Cu I-和 Ru II 催化的叠氮化物-炔 [3+2] 环加成作为中心步骤的模块化合成路线。为了演示该方法,我们准备了一个包含所有三个支架的化合物库。
