CHIRAL BICYCLIC SPIROPHOSPHORANES IN AN ARBUZOV-TYPE REACTION

The reaction of 2-hydroxy-5-nitro-benzyl halides with three chiral five-or six-membered oxaphosphacycloalkanes has been studied.In each case, a 31P NMR analysis shows the formation of resonance signals in the phosphorane region but these phosphoranes are usually unstable.However both enantiomers of the 2-phenyl-1,3,2-oxazaphospholidine give chiral bicyclic spirophosphoranes which have been characterized by 31P and 1H NMR and high resolution mass spectroscopies.
