A novel 3,4,4a-trihydroxanthene-fused pyrrole 2 was synthesized by the reaction of 2,3,4,4a-tetrahydro-1H-xanthen-1-one with 3-phenyl-2H-azirine in the presence of LDA. Utilizing this pyrrole 2, a NIR BODIPY 1 (λabs = 732 nm, λem = 747 nm) has been prepared. The new BODIPY 1 was stable, non-cytotoxic, and suited to labeling living cells for imaging assay in the NIR region.
通过2,3,4,4a-四氢-1H-呫吨-1-酮与3-苯基-2H-吖丙啶在LDA存在下反应合成了新型3,4,4a-三氢呫吨稠合吡咯2。利用该吡咯 2,制备了近红外 BODIPY 1(λabs = 732 nm,λem = 747 nm)。新型 BODIPY 1 稳定、无细胞毒性,适合标记活细胞以进行近红外区域的成像分析。
