Abstrakt:	Regiospecific replacement of the 4''‐ and 6'‐nitro groups in the tetranitroquaterphenyl (I) by isopropyloxy groups is effected in two ways; the resulting product (V) is converted to a separable mixture of the two cyclic phosphinic meso esters (VIII) and (IX) and the racemic ester (X); the latter is resolved on a chiral HPLC column.
