摘要：
A method for making arthropodicidal oxadiazines and intermediates which are racemic or enantiomerically enriched at their chiral center, the method for making the oxadiazines comprising reaction of an intermediate selected from ##STR1## wherein: R.sup.1 is F, Cl, or C.sub.1 -C.sub.3 fluoroalkoxy,R.sup.2 is C.sub.1 -C.sub.3 alkyl, andR.sup.4 is H or CO.sub.2 CH.sub.2 (C.sub.6 H.sub.5).as well as certain selected intermediates including those depicted above, and methods of making them.
