Abstract
A new class of phosphines in which the phosphorous atom is bonded directly to the carbon of an oxazinone: ##STR1## In addition to their anti-inflammatory activity, these phosphines are useful as intermediates in producing compounds where the phosphine is replaced by a benzylidine, compounds which have also been proven useful in the treatment of inflammation and other conditions associated with arthritis.
