The acid mediated ortho-iodination of Weinrebamidesusing a readily available catalyst is described. The selective ortho-iodination of Weinrebamides, challenging substrates in directed C–H activations, and also of benzamides is achieved. The process works under mild conditions and tolerates air and moisture, having a great potential for industrial applications. The methodology can be applied under
To investigate the mechanism of action of the potent antiviral compound PD 404182, three novel photo-affinity probes equipped with a biotin or alkyne indicator were designed and synthesized based on previous structure-activity relationship studies. These probes retained the potent anti-HIV activity of the original pyrimidobenzothiazine derivatives. In photoaffinity labeling studies using HIV-1-infected H9 cells (H9IIIB), eight potential proteins were observed to bind PD 404182. (C) 2013 Elsevier Ltd. All rights reserved.
