Mixed-metal ethylenediaminetetraacetates of neodymium and alkaline earths

Conclusions In solution, the complexes M^II(NdA)₂ do not have a polynuclear structure. In the conditions studied, hydroxo polynuclear complexes including EDTA and M^II and Nd³⁺ ions are also not formed. Our results are not inconsistent with the hypothesis that the solid complex Ca(NdA)₂·17H₂O has a polynuclear structure and that the polynuclear character is successively weakened as Ca²⁺ is replaced by Sr²⁺ and Ba²⁺.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1235–1239, June, 1977.     

Stereochemistry of the synthesis of 1,2,3,4-tetrahydrocinnolines from aryldiazenium salts and olefins

It follows from the PMR spectra that the reaction of 1-methyl-, 1-phenyl-, 1-ethyl-,1-phenyl-, and 1,1-diphenyldiazenium salts with cis- and trans-d-styrenes, which leads to the corresponding 3-d-4-phenyl-1,2,3,4-tetrahydrocinnolines, takes place with retention of the configuration in the starting styrenes. It is therefore proposed that this reaction be regarded as a special case of [4⁺_s + 2_s]-cycloaddition.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1658–1661, December, 1977.

Synthesis of methylamides of O-(2-acetamido-2-desoxy-Β-D-glucopyranosyl)-N-acetylserine and O-(2-acetamido-2-desoxy-Β-D-glucopyranosyl)-N-acetylthreonine

Conclusions The oxazoline method was used to synthesize the methylamides of O-(2-acetamido-2-desoxy--D-glucopyranosyl)-N-acetylserine and O-(2-acetamido-2-desoxy--D-glucopyranosyl)-N-acetylthreonine.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 697–699, March, 1975.
