The present invention relates to a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing the same as an active ingredient. The method for preparing a biomaterial to which a compound represented by formula 2 is coupled, of the present invention, allows the compound represented by formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient. In addition, the method can selectively functionalize tyrosine, and thus can be effectively used for tyrosine functionalization in a biomaterial.

nitration of 3‐substituted indoles, by using the economical and non‐toxic cobalt nitrate hexahydrate [Co(NO3)2⋅6 H2O] as a catalyst and tert‐butyl nitrite (TBN) as the nitro source, is reported. This approach provides a unique methodology involving a site‐selective C−N bond formation for preparation of C‐2 substitutednitro indoles. Utilization of the tBoc as the removable directing group enhances the
温和和有效的C(SP 2)-H的3-取代的吲哚硝化,通过使用经济,无毒的六水合硝酸钴[Co(NO 3)2 ⋅ 6 H 2 O]作为催化剂,叔丁基亚硝酸盐报道了以(TBN)为硝基源。这种方法提供了一种独特的方法,该方法涉及制备C-2取代的硝基吲哚的位点选择性C-N键形成。将t Boc用作可去除的导向基团增强了该方法的合成效用。
