Synthesis of a Sensitive and Selective Potassium-Sensing Fluoroionophore
摘要:
An efficient synthesis Is reported that delivers in 5 steps and 52% overall yield a new structurally simplified fluorescent K+ sensor with Improved K+ sensitivity and selectivity over existing K+ sensors. The synthesis procedure utilizes a new template-directed oxidative C-N bond-forming macrocyclization reaction and reports new approaches to Pd(0), Sandmeyer-like and metal-free aminoarylations, as well as organotitanlum additions to vinylogous sulfonates.
