The synthesis, in racemic form, of the insect juvenile hormone inhibitor brevioxime (1) is described, as well as exploratory studies that led to the relatedmodelcompounds 14 and 15a. The route to 1 involves Ag(+)-mediated coupling of the amine derived from 20 with the beta-keto thioester 32. Acid treatment of the coupled product 33 led by acetal hydrolysis, cyclization, and desilylation to 34a,b

Sulfuryl chloride is a convenient reagent for the allylic chlorination of olefins bearing an isopropenyl or isopropylidenyl moeity. The substitution occurs with good yields and with allylic rearrangement, giving in most cases a secondary chloride.
