AZINES -- BIFUNCTIONAL REAGENTS -- CYCLOADDUCTS
Аннотация: Reactions of azines with bifunctional nucleophiles can give rise to several cycloadducts, the structure depending on the nature of reagents, the structure of the azine substrate, and the reaction conditions. Three types of cycloadducts are proposed to be formed in reactions of azines with such 1,3-N,C-dinucleophiles as acetamidines and acetimino esters. Ortho-cyclization products can usually be isolated, while meta- and para-bridged cycloadducts are unstable and are often transformed into other heterocyclic systems. Their presence as intermediates can, however, often is rationalized by spectroscopic methods or 15N-labeling studies. Many of the reactions discussed provide a very convenient synthetic route to a great variety of azine derivatives. It seems to be a very interesting and promising area of heterocyclic chemistry and there is no doubt that further investigations into this field also allow new syntheses of useful compounds to be developed

1,2,4-TRIAZINES -- NITROGEN-CONTAINING HETEROCYCLES
Аннотация: Among the six-membered nitrogen-containing heterocycles the 1,2,4-triazines have attracted the attention of chemists for a long time. This is due to the fact that many 1,2,4-triazine derivatives are biologically active and are used in medicine and agriculture. Moreover, 1,2,4-triazines are of chemical interest. They proved to be very susceptible to attack by all kinds of nucleophiles, leading to the addition, and subsequently either substitution or cyclization, and ring transformation. This continuing and lively interest in this area of heterocyclic chemistry has produced a great number of publications and patent applications. This chapter concentrates on the behavior of monocyclic 1,2,4-triazines in reactions with C-, N-, 0-, and S-nucleophiles, because the important features of general character established for simple 1,2,4-triazines can evidently be applied to other derivatives including condensed 1,2,4-triazines.

TETRAHYDROPYRAZINES -- DISSOCIATION REACTION
Аннотация: Based on a study of electron impact mass spectra of a large number of tetrahydropyrazines, which are joined to five- and six-membered heterocyclic and carbocyclic residues, the trends which characterize the stability of these condensed systems are found. The proposed criteria can be used for evaluation of the chemical stability of these compounds, for example, their propensity toward the reverse dissociation reaction.

ACRYLIC ACID DERIVATIVE -- PYRAZOLE -- TUBERCULOSTATIC AGENT
Аннотация: A rapid development of the resistance of drugs and their toxic and adverse reactions suggest that new antituberculous drugs should be designed. Of the greatest importance is isoniazid resistance. Testing new compounds (IIa, b) has established that the minimum inhibitory concentration of the drug (IIa), 0.39 microgram/ml suppresses the growth of Mycobacterium tuberculosis (MBT) in the macrophages up to 50%, that of the drug (IIb), 1.56 micrograms/ml, causes death in 25% of cases, which is indicative of the high activity of compounds (IIa, b) against MBT

Аннотация: We have discussed the grounds of modern understandings about S reactions. Quite recently??N??they used to be associated with Chichibabin reaction,hydroxylation of nitrobenzene,synthesis of??alizarin,i.e. with the processes occurring under stringent conditions,what is natural in terms of the??- high-energy nature of the displaced H particle. This situation did not stimulate chemists to investi-??gate this area. This pattern entirely changed today. Modern data on the reaction mechanism give a??clear idea of a necessity to fulfil an indirect removal of the hydride ion. This knowledge has undeni-??ably contributed much to the progress in this field of research through development of diverse and??H??convenient synthetic methods with the use of S??reactions.??N
