Novel Insect-Repellent Coumarin Derivatives, Syntheses, and Methods of Use
-
Page/Page column 23, (2013/02/28)
This invention relates to novel coumarin derivative, formulations comprising same, and to methods of making and using these compounds and formulations, which are useful as repellents against insects and/or pests. The compounds also prevent illness and disease caused by insect/pest-borne vectors, and provide safer, more effective alternatives to existing repellents.
Photodimerization of Coumarins in Micelles: Limitations of Alignment Effect

Organized media such as micelles have shown great promise in achieving regio- and stereoselectivity in photochemical cycloaddition reactions as has been shown by recent reports. 7-Alkoxy- and 4-methyl-7-alkoxycoumarins dimerize in organic solvents to give the syn head-tail dimer.However, dimerization of these coumarins in SDS and CTAB micelles did not show any reversal in this trend.The results probably indicate that the micellar orientational effect is most effective only in those systems where the forces that control regiochemistry are weaker than hydrophobic association energies.
