The present invention relates to a composition having the general formula: ##STR1## wherein each of A, B, C, X, Y, and Z is independently O, NH, N(CH.sub.2).sub.m CH.sub.3, N(C.dbd.O) (CH.sub.2).sub.m CH.sub.3, CH.sub.2, S, or Se; each of R.sub.1, R.sub.2, and R.sub.3 is independently phenyl, 4-hydroxyphenyl, pyridyl, pyrrolyl, indolyl, naphthyl, thiophenyl, (C.dbd.O) (CH.sub.2).sub.p CH.sub.3, NH(C.dbd.O) (CH.sub.2).sub.p CH.sub.3, OH, COOH, NH.sub.2, or SH; and m, n, and p are integers between 0 and 5. The composition is a chiral receptor molecule useful for the purification of enantiomers of derivatives of amino acids and of compounds able to form hydrogen bonds. The preparation of the composition involves coupling a trifunctional aromatic molecule with three protected chiral molecules at the three aromatic groups, cleaving protecting groups, and joining adjacent chiral groups by multiple lactamizations. The receptor may be used in a form either bound to a solid support or dissolved in an immiscible phase to effect convenient purification of enantiomers or other compounds of interest.

摘要:
There are disclosed certain novel compounds identified as benzo-fused macrocycles which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused macrocycles as the active ingredient thereof are also disclosed.
