Eight-Membered Rings With Two Heteroatoms 1,2
2022
The chapter titled “Eight-membered Rings with two Heteroatoms 1,2” deals with heterocine rings with two heteroatoms in a 1,2 relationship, namely 1,2-diazocine, 2H-1,2-oxazocine, 2H-1,2-thiazocine, 1,2-dioxocin, 1,2-oxathiocin and 1,2-dithiocin. This article covers the literature from 2007 to 2019 and reports the chemistry of uncondensed derivatives, heterocines fused to carbocycles and heterocycles, as well as bridged heterocines. As usual, in the case that a particular section is not mentioned, it means that no chemistry has been reported. In this article, the “Biosynthesis” paragraph was additionally introduced, since in the latest years the contribution of Nature to the synthesis of dih…
Eight-membered heterocycles with two heteroatoms in a 1,5-relationship of interest in medicinal chemistry
2020
Abstract This review deals with 1,5-diheterocines that exhibited biological properties and covers comprehensively the literature from 2007 to the end of February 2019. Among the six possible heterocyclic systems belonging to the eight-membered rings with two heteroatoms, N, O, and S, five had derivatives showing pharmacological activities: 1,5-diazocines, 1,5-oxazocines, 1,5-thiazocines, 1,5-dioxocins, and 1,5-dithiocins. Instead, literature reported no articles dealing with 1,5-oxathiocins of interest in medicinal chemistry. In addition to uncondensed derivatives, 1,5-diheterocines fused to five- and six-membered carbocycles or heterocycles are covered. Bridged 1,5-diheterocines are covere…
A facile synthesis of 1-ethyl-3-methyl-11-phenyl-1,4-dihydro-5H-pyrazolo[3,4-c][1,5]benzodiazocin-5-ones. A new ring system
2007
The new ring system pyrazolo[3,4-c][1,5]benzodiazocine was obtained through cyclization of the key intermediate of type 6a-d and 9, in refluxing toluene in presence of a catalytic amount of p-toluensulfonic acid, from moderate to high yields
Eight-Membered Rings With Two Heteroatoms 1,3
2022
Eight-membered rings with two heteroatoms in a 1,3-relationship, namely 1,3-diazocine, 2H-1,3-oxazocine, 2H-1,3-thiazocine, 4H-1,3-dioxocin, 4H-1,3-oxathiocin, and 4H-1,3-dithiocin, are discussed in this chapter, that covers the literature from 2007 to October 2020 (SciFindern search) and reports the chemistry of uncondensed derivatives, heterocines fused to carbocycles and heterocycles, as well as bridged heterocines. Among eight-membered 1,3-diheterocines, 1,3-diazocines and 1,3-oxazocines are the two largest classes, based on the number of publications, mostly due to the studies of the synthesis of these cyclic systems, their pharmacological properties and/or their important industrial a…
Eight-membered heterocycles with two heteroatoms in a 1,3-relationship of interest in medicinal chemistry
2022
This chapter deals with 1,3-diheterocines, eight-membered heterocyclic systems with two heteroatoms, N, O and S, in a 1,3 relationship, exhibiting biological properties and exhaustively covers the literature from 2007 to the end of November 2019. The biological results of 1,3-diazocines, 1,3-oxazocines, 1,3-dioxocins and 1,3-thiazocines, that are the largest class of 1,3-diheterocines, were collected together with the few results available for 1,3-oxathiocin and 1,3-dithiocin derivatives at that time.
Eight-membered heterocycles with two heteroatoms in a 1,2-relationship of interest in medicinal chemistry
2021
Abstract This chapter treats 1,2-diheterocines, eight membered heterocyclic systems with two heteroatoms, N, O and S, in an 1,2 relationship, exhibiting biological properties and exhaustively covers the literature from 2007 to the end of November 2019. In this period of time 1,2-diazocine, 1,2-oxazocine, 1,2-dioxocin and 1,5-dithiocin ring systems had derivatives exhibiting pharmacological activities. No articles on biological properties have been reported for 1,2-thiazocines and 1,2-oxathiocins. Besides uncondensed derivatives, 1,2-diheterocines fused with five-, six-, and seven-membered carbocycles or heterocycles have been reviewed, as well as bridged 1,2-diheterocines.
Eight-Membered Rings With Two Heteroatoms 1,5
2022
This chapter titled “Eight-membered Rings with two Heteroatoms 1,5” deals eight-membered rings with two heteroatoms in a 1,5-relationship, namely 1,5-diazocine, 1,5-oxazocine, 1,5-thiazocine, 1,5-dioxocin, 1,5-oxathiocin, and 1,5-dithiocin and covers the literature from 2007 to October 2020 (SciFindern search) reporting the chemistry of uncondensed derivatives, diheterocines fused to carbocycles and heterocycles, as well as bridged diheterocines. Among them, the 1,5-diazocine ring system is by far the largest class, based on the number of publications which constituted the 87% of the total amount of the references reported in the range of interest of CHEC IV. Thus, 1,5-diazocines were divid…
