Compounds that have agonist activity at one or more of the SlP receptors are provided. The compounds are sphingosine analogs that, after phosphorylation, can behave as agonists at SlP receptors.
A simple and efficient method for radical hydrodeiodination is reported. The novel approach uses electron catalysis. In situ generated Na‐alcoholates are introduced as radical chain reducing reagents and reactions work with O2 as cheap initiator. Hydrodeiodination works on aryl, alkenyl, alkynyl iodides and a tert‐alkyliodide also gets reduced applying the method. Albeit less general, the method is
