Аннотация: The cyclization of N-methylquinoxalinium iodide with ammonium salts of N-alkyl-dithiocarbamic acids in DMSO leads to 4-methyl-2,3,3a,4,9,9a-hexahydrothiazolo-[4,5-b]quinoxalines, whereas regioisomeric cycloadducts with a reversed orientation of the thiazole ring are formed in ethanol in the presence of diethylamine.

ISOMERIZATION -- CHLOROFORM -- QUINOXALINIUM CATION
Аннотация: 4-Alkyl-2-phenyl-3a,4,9,9a-tetrahydrothiazolo[4,5-b]quinoxalines undergo isomerization in chloroform in the presence of acids to the regioisomeric (with respect to them) 9-alkyl-substituted derivatives. Under the same conditions 2,4-dimethyl-3a,4-9,9a-tetrahydrothiazolo [4,5-b]quinoxaline undergoes isomerization to 4-methyl-1H-2,3,3a,4,9,9a-hexahydropyrrolo[2,3-b]quinoxaline-2-thione. It was demonstrated by means of deuterium labels that in both cases the isomerization proceeds through a step involving dissociation to a quinoxalinium cation and the corresponding thioamide

Аннотация: A series of new tricyclic fluoroquinolones was prepared by replacing fluorine atoms in derivatives of 2-R-8-Y-7-oxo-9,10-difluoro-7H-1,3,4-thiadiazino[6,5,4-i,j]quinoline-6-carboxylic acids. In acids and esters containing a hydrogen atom in position 8 occurred replacement of F10 by amine rests, and in compounds with a fluorine in position 8 was substituted either F8or F10 and F8depending on the amine character

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

Аннотация: General method for preparation of high yields of novel N-protected carborane amino acid derivatives, 3-acylamino-1-carboxymethyl-2-R-o-carboranes (R = H, Me, Ph), is reported. The synthesis starts from readily available 3-amino-o-carboranes and includes the protection of amino group, introduction of carboxymethyl function to the carbon atom of polyhedron via the metallation of carborane CH bond with sodium amide in liquid ammonia, and treatment of corresponding sodium carboranes with sodium bromoacetate. Deprotection of N-acylated carborane amino acids is studied in acidic media. Depending on the procedure employed, closo- or nido-carborane amino acids were obtained
