The present invention relates to chemokine receptor binding compounds, pharmaceutical compositions and their use. More specifically, the present invention relates to modulators of chemokine receptor activity, preferably modulators of CCR5. These compounds demonstrate protective effects against infection of target cells by a human immunodeficiency virus (HIV).

products as well as building blocks for chemical synthesis. Developing efficient methods for the synthesis of diverse 1,3-dienes from simple starting materials is therefore highly desirable. Herein, we report a Pd(II)-catalyzed sequential dehydrogenation reaction of free aliphatic acids via β-methylene C–H activation, which enables one-step synthesis of diverse E,E-1,3-dienes. Free aliphatic acids of
