γ-Lactams (pyrrolidin-2-ones) and products containing the γ-lactam core are important synthetic targets and often display interesting biological activities, so that the development of improved synthetic methodologies for their preparation has become the objective of many synthetic chemists. This review is presented in two parts: Part I highlights efficient synthetic strategies (issued between 2001 and 2013), which are Read More

The physiological importance of proteins that can regulate ion balance and transmembrane transport is highlighted by different diseases where ion channel dysfunction is observed. During the past two decades, considerable effort has been devoted to develop synthetic ionophores that can insert or cross cell membranes and restore the dysfunction of highly complex protein channels. Not withstanding the remarkable structu Read More

Mono- and difluoromethylenebisphosphonates are of great synthetic and biological interest since they are among the best isopolar pyrophosphate mimics. This review will emphasize preparation and some of the most important applications of these compounds. The following synthetic approaches to fluoromethylenebisphosphonates are summarized: (i) electrophilic halogenation, (ii) Arbuzov and Michaelis-Becker reactio Read More

Clarification of the confusion previously reported will prevent the proliferation of scientific mistakes and consequently avoid a negative domino effect due to today’s rapid divulgation of information. The complex structures of asperjinone, (+)-pestalazine B and aquatolide have been revised in recent years and these studies have been included herein. However, there may be some misunderstanding on simpler structures such a Read More

The application of 9,10-dihydroanthracene in a sequence of dehydrogenation/Diels-Alder cycloaddition reactions with a variety of N-substituted maleimides is described. The in situ transformation of the 9,10-dihydroanthracene into the corresponding anthracene, which is acting as a diene, is accelerated by activated carbon (Darco® KB). The anthracene/maleimide cycloadducts thus obtained might offer some important bioch Read More
