Synthesis of (E)-9-(1-pyrenyl)-4-hydroxynon-2-enal, a fluorescent probe of the (E)-4-hydroxynon-2-enal with retained biological properties
摘要:
(E)-9-联苯基-4-羟基-非二烯醛(FHNE)是(E)-4-羟基-非二烯醛(HNE)的荧光探针。通过分七步合成,总产率为35%,从商品化的1-磷酸二酯苯基醛(I_PA)出发制备。将其与HeLa细胞共同培养时,该荧光探针可穿透细胞并与细胞核周围聚集。作为母化合物,HNE诱导热休克因子(HSF)的激活,且诱导HSF与热休克元件(HSE)结合。 (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.

The selective deoxygenation of polyols is a frontier in our ability to harness the stereochemical and structural complexity of natural and synthetic feedstocks. Herein, we describe a highly active and selective boron‐based catalytic system for the selective deoxygenation of terminal 1,2‐diols at the primary position, a process that is enabled by the transient formation of a cyclicsiloxane. The method
