Synthesis and crystal structure of Δ6-4-methyl-5,6-diphenyl-5-hydroxy-1,2,4-triazacyclohexene-3-thione, a 1-dimensional supramolecule
摘要:
Condensation of N(4)-methylthiosemicarbazide, as well as substitution by the N(4) function, leads to a cyclized product. The triazacyclohexene ring is essentially planar, and the two attached phenyl rings are turned out of its plane. The molecule via its intermolecular hydrogen bonding forms a supramolecular structure. The crystal data are: C16H15N3OS, monoclinic, P2(1)/c, a=14.8668(10)Angstrom, b=6.1619(4)Angstrom, c=16.6700(17)Angstrom, beta=106.190(8)degrees, V=1466.5(2)Angstrom(3), Z=4.

乙二醛亚硫酸氢钠加成化合物与2,4-二氨基戊烷二盐酸盐反应生成5,7-二甲基六氢-1,4-二氮杂-2--2-酮,但乙二醛一水合物在碱性条件下与1,3-二氨基丙烷和2,4-二氨基戊烷反应产生更复杂物质的条件。环己烷-1,2-二酮与1,3-二氨基丙烷缩合形成2,3,4,6,7,8-六氢-1 H -1,5-苯并二氮杂,,但二亚胺由两个二羰基化合物分子形成1,3-二氨基丙烷与苯甲酰,樟脑醌和靛红的反应产生了二胺之一。复杂的产品是从邻醌和二氨基丙烷获得的。1,3-二酮和1,3-二胺反应生成由两个酮分子和一个胺分子形成的开链化合物。2,3-二氢-1 H-1,4-二氮杂apparent显然是由丙二醛和乙二胺形成的,但是1,2-二氨基环己烷与丙二醛反应生成1,2-双(2-甲酰基乙烯基氨基)环己烷。
Reactions of 1,3-propanediamine with alpha-dicarbonyl compounds (1a-e) were examined and various condensed heterocyclic compounds such as 1,4-diazepines (2) and 3-pyrimidine derivatives (3) were obtained. Some of 1,4-diazepines (2) showed DNA strand breakage activity.
