A spiral armor manman ester and intermediate preparation method

The invention discloses a spiral armor manman ester and intermediate preparation method, the spiral armor manman ester intermediate is 3 - (2, 4, 6 - trimethyl-phenyl) - 2 - oxo - 1 - oxaspiro [4, 4] nonyl - 3 - ene - 4 - ol, preparation method comprises the following steps: hydroxy cyclopentyl formic acid ethyl ester, 2, 4, 6 - trimethyl phenyl acetic acid in under the action of a dehydrating agent, to carry out the esterification, then generate the cyclization reaction, generating 3 - (2, 4, 6 - trimethyl-phenyl) - 2 - oxo - 1 - oxaspiro [4, 4] nonyl - 3 - ene - 4 - ol. The process short reaction time, the reaction temperature is low, can obviously very high yield.

Spirodiclofen and spiromesifen - Novel acaricidal and insecticidal tetronic acid derivatives with a new mode of action

The broad spectrum acaricides spirodiclofen (BAJ2740, trade name: Envidor) and spiromesifen (BSN2060, trade name: Oberon) with an additional excellent activity against whiteflies, both belong to the new chemical class of tetronic acid derivatives discovered at Bayer CropScience during the 1990s. The discovery process starting from herbicidal PPO (protoporphyrinogen oxidase) chemistry, the synthetic routes leading to the products, and some insight into process development of central intermediates is given. Spirodiclofen and spiromesifen have a new mode of action (interference with lipid biosynthesis), show no cross-resistance to any resistant mite or whitefly field population and are therefore valuable tools for resistance management.
