A nickel-catalyzed intramolecularaddition of aryl halides to 1,3-diketones was first developed. This desymmetrization reaction afforded polycyclic products bearing two tetrasubstituted centers with excellent diastereoselectivities and high yields. Moderate enantioselectivities were achieved in the presence of a chiral ligand. This transformation has great potential for the synthesis of polycyclic
The invention relates to compounds selected from the group consisting of the formulas: ##STR1## wherein R.sup.2 and Ph are as described herein. These compounds are potent leukotriene B.sub.4 antagonists and are therefore useful in the treatment of inflammatory diseases.
