The invention relates to a method of controlling insects (in particular insects of the order Hemiptera, especially aphids and whitefly) that are resistant to neonicotinoid insecticides, to methods of controlling insects whereby undesired insects are affected but beneficial arthropods are not affected, using compounds of formula I(where A and R1 are as defined above) and, further, to novel compounds of formula I which are useful in the aforementioned methods and/or which possess enhanced insecticidal properties, and to compositions containing said compounds.

A compound of formula (I), wherein A and R1 are as defined in claim 1. Furthermore, the present invention relates to intermediates used to prepare compounds of formula (I), to methods of using them to combat and control insect, acarine, nematode and mollusc pests and to insecticidal, acaricidal, nematicidal and molluscicidal compositions comprising them.

Scopolamine was synthesized using 6,7-dehydrotropine as a key intermediate. Rhodium-catalyzed [4 + 3] cycloaddition chemistry and a modified Robinson–Schopf reaction were each independently evaluated for their utility in constructing the tropane core. Both synthetic approaches gave comparable overall yields.
A compound of formula I, (I), wherein A, Q, R1, and R2, are as defined in claim 1. Furthermore, the present invention relates to intermediates used to prepare compounds of formula (I), to methods of using them to combat and control insect, acarine, nematode and mollusc pests and to insecticidal, acaricidal, nematicidal and molluscicidal compositions comprising them.
