2,1-Bensoidoxazoles [anthranils]. Synthesis and opening of the isoxazole ring (review)
The present review covers the literature on the synthesis of 2,l-benzoisoxazoles (anthranils) (I), and reactions of this bicyclic system which involve opening of the isoxazole ring. Since a detailed and satisfactorily full review of the chemistry of 2, l-benzoisoxazoles was published in 1967 [96], the main thrust of the present review is to cover the literature of the last twenty years. It has nevertheless been necessary to include earlier publications, especially when these deal with general methods of synthesis of anthranils. t i. Synthesis of 2~l-Benzisoxazoles
Ring opening reactions of 6H‐anthra[1,9‐cd]isoxazol‐6‐ones and related compounds
Nucleophilic attack of anthra[1,9-cd]isoxazol-6-ones, and of anthra[1,9-cd:5,10-c'd']isoxazole by various sulfoxides, triphenyl phosphine, and aliphatic or aromatic phosphites proceeded with cleavage of the nitrogenoxygen bond of the isoxazole ring. This method provided ready access to substituted anthraquinones bearing sulfoximido-, triphenylphosphazo-, and dialkyl(aryl)phosphoramidic groups attached to the 1- and the 1,5-positions of the anthraquinone system. The structures of the newly synthesized anthraquinone derivatives were supported by analytical and spectral data. l-S,S-dimethyl-N-(5-benzamidoanthraquinon-1-yl)-sulfoximide yielded in 90% sulfuric acid the l-amino-5-sulfoximido anthraquinone without hydrolyzing the sulfoximido group.
Main tendencies of religious consciousness development in modern society
The article is devoted to the investigation of the tendencies of religious consciousness development in modern society. At the present stage of development religious consciousness, like any other social and psychological phenomenon, is undergoing significant changes. The development of religious consciousness at the present stage of society evolution leads to the development of common moral norms and requirements. There is a tendency to reduce human ties with the religious community as a translator of religious consciousness. It is possible to speak about the transformation of religious consciousness but not about its disappearance.
