- Bicyclic heterocyclic anthranilic diamides as ryanodine receptor modulators with insecticidal activity
-
The diamide insecticides act on the ryanodine receptor (RyR). The synthesis of various bicyclic anthranilic derivatives is reported. Their activity against the insect ryanodine receptor (RyR) and their insecticidal activity in the greenhouse is presented,

- Photoinduced Nitro-Nitrite Rearrangement of 5-Nitroquinoxalines
-
Unlike known o-nitro methyl derivatives of aromatic compounds, 6-methyl-5-nitro-, 2,3,6-trimethyl-5-nitro-, and 7-methyl-6-nitroquinoxaline and 1,6-dimethyl-5-nitroquinoxalinium perchlorate do not exhibit photochromism in aqueous-ethanolic solutions under conditions of flash photolysis with a time resolution of 50 μs. Under conditions of continuous photolysis, these 5-nitromethylquinoxaline derivatives and also 5-nitroquinoxaline undergo nitro-nitrite rearrangement to give 5-quinoxalinol derivatives with quantum yields ranging from 1 × 10-4 to 3 × 10-3; the efficiency of the photochemical reaction increases when irradiation is performed with a shorter-wave light. 6-Nitro derivatives do not form stable products of photochemical transformations under the same conditions.
