Isolation and Crystal Structure of Trans-2,2'''',4,4''''-tetramethyl-6,6''''-dinitro Azobenzene

1 INTRODUCTION The aconitum plants produce various diterpene and norditerpene alkaloids[1, 2]. Up to now more than 450 diterpenoid and norditerpenoid alkaloids have been isolated from the roots of this genus[3]. Sub- sequent studies on the flower of the same subspecies were directed to the other secondary metabolites such as flavonoids[4, 5]. The flavonoidic composi- tions of several oriental species of A. plants have been reported[6～8]. A. sungpanense hand. Mazz., a very highly poi- s…     

Synthesis and Crystal Structure of (p-{2-[p-(5''''-Phenyl-1'''',3'''',4''''-oxadiazole-2''''-yl)-phenyl]- vinyl}-phenyl)-di-p-tolyl-amine

1 INTRODUCTION Triarylamines constitute a well known class of hole conducting material[1～4]. On the other hand , oxadiazole-based compounds as good electron- transporting materials[5,6] have played an important role in the fabrication of multiple-layer light- emitting diode devices. It is well known that, to achieve good performance in electroluminescence (EL) devices, the injection of electron and hole should be in balance[7]. The requirement might be met in a new compound containing …     

Crystal Structure of 10-(2'''',5''''-Dimethoxybenzylidene) Anthrone

1 INTRODUCTION The 10-benzylidene anthrones which are important intermediate for organic syntheses[1～3] usually possess thermochromism[4] and photo- chromism[5], and have been found recently to have evident anti-cancer activity[6]. We found that the substituents in the phenyl ring will affect the bioactivity of those compounds. For more deeply investigating the structure-activity relationships (SAR) and understanding interactions between the three dimensional structure of the compound …

Synthesis and Crystal Structure of 2-Benzylamino-6-methyl-3-cyano-8- phenyl-5H-bispyrazolo[3,4-d,3'''',2''''-b]pyrimidine

1 INTRODUCTION The pyrazolopyrimidines have attracted conside- rable attention due to their versatile physiological activities, and a number of them exhibit excellent fungicidal[1], antiphlogistic[2～4] and antiumor[5] acti- vities. However, our interest in pyrazolo- pyrimidine stems is their applications as bactericide[6]. Herein we report the synthesis and structure of a tricyclic ring system bispyrazolo[3,4-d, 3?,2?-b]pyrimidine 1. 2 EXPERIMENTAL The 1H NMR spectra (CDCl3) were …
