Insecticidal anthranilic diamides: A new class of potent ryanodine receptor activators
摘要:
A novel class of anthranilic diamides has been discovered with exceptional insecticidal activity on a range of Lepidoptera. These compounds have been found to exhibit their action by release of intracellular Ca2+ stores mediated by the ryanodine receptor. The discovery, synthesis, structure-activity, and biological results are presented. (c) 2005 Elsevier Ltd. All rights reserved.
Novel diarylpyrimidine derivatives and pharmaceutically acceptable salts, solvates or hydrates thereof, designed to inhibit HIV reverse transcriptase, are provided, and a pharmaceutical composition containing the same, especially an anti-HIV agent.

The inverse electron demand hetero-Diels-Alderreaction of methoxymethylene substituted 1.3-dicarbonyl compounds with enol ethers and enediol ethers results in the selective formation of 3.4-dihydro-2H-pyrans. These adducts with a high density of functional groups are versatile intermediates for natural product syntheses.
Origins of glaucophanic enol in certain ‘melt’ reactions

DOI:10.1039/c39800000211
日期:——
Chemical and [14C]-labelling studies lead to interdependent mechanisms for the formation of glaucophanic and xanthophanic enols; the scheme is supported by consideration of the effects of different alkoxy-methylene compounds on the relative yields of glaucyrones and xanthyrones.
