The analogue of zeatin bearing a vinylic fluorine atom and its geometrical isomer were synthesized. The fluorine atom exerts a favorable influence on cytokinin activity in the fluoro analogue of cis-zeatin, but not in the fluoro analogue of zeatin it

In chlorophosphorothionate or dichlorophosphorothionate esters, Hg(II)-coordination to the S-atom facilitates nucleophilic attack at P of the azide ion, to afford the corresponding azido derivatives in good yields. The chemoselectivity of this reacti

A diazoketone 3 has been synthesized in two steps from acifluorfen 1, a diphenyl ether herbicide. Like the parent compound 1, the diazoketone 3 is toxic to plant cells and inhibits protoporphyrinogen oxidase, the molecular target of diphenyl ether he

(±)-Methyl nonactate (2) and (±)-methyl 8- epi -nonactate (3), synthetic precursors to the antibiotic nonactin have been synthesised, employing the reaction of substituted epoxides with dianions derived from β-ketoesters as the key carbon—carbon

Presented here are several examples which demonstrate that ether substituents α- or β- to an epoxide ring can be tolerated in the ring-opening reaction with β-keto ester dianions. Subsequent acid-promoted cyclisation of the γ-hydroxy β-ketoester
