Abstract
The reaction of 1,7,7-trimethylbicyclo[2.2.1]heptane-2,3-dione with hexaethyltriamido-phosphite in the presence of diethylammonium chloride afforded a stable quasiphosphonium salt, viz., (1,7,7-trimethyl-2-oxobicyclo[2.2.1]hept-3-yloxy)tris(diethylamino)phosphonium chloride, as one diastereomer (racemate, 1R*,3S*,4S*).
