The application of a monolithic form of triphenylphosphine to the Ramirez gem-dibromoolefination reaction using flow chemistry techniques is reported. A variety of gem-dibromides were synthesised in high purity and excellent yield following only removal of solvent and no further off-line purification. It is also possible to perform the Appel reaction using the same monolith and the relationship between the mechanisms of the two reactions is discussed.

The synthesis of a highly functionalised decalin fragment (2) of the antifeedant azadirachtin (1) is described. A silyl group was employed to control the stereoselectivity of several key steps and to introduce C3 hydroxyl functionality. A novel ring contr
