Synthesis of (strained) macrocycles by sulfone pyrolysis,xide (“sulfone pyrolysis”) is of general importance because it offers access to a large diversity of macrocycles not equalled by other methods. Highly strained macrocycles as well as macrocycles containing labile moieties or functional groups can be synthesized. Several bonds can be created simultan

Ring closure methods in the synthesis of macrocyclic natural products, macrocyclic natural products and, to some extent, their model compounds. However, not only macrolides, but all kinds of macrocyclic natural products which have been synthesized by ring closure reactions are covered. The commonly used ring closure methods in recent literature include those involving

Expanded porphyrins,ntaining systems, the so-called “expanded porphyrins”, have received considerably less attention. Such systems, by virtue of containing a greater number of π electrons, a greater number of donating (e.g. pyrrolic) groups, or a larger central binding core, however, might have properties which differ

t formative social ties involved only other humans, reflecting an anthropocentric bias. However, by the closing decades of the twentieth century, studies calling attention to “the human-animal bond” coalesced into a nascent field (c. 1987) and the study of non-human animals in the lives of children
