Filed:

Dec 9, 1999

Appl. No.:

9/458229

Inventors:

Zhisheng Dai - Edison NJ
Meng J. Chen - Edison NJ

Assignee:

Cardolite Corporation - Newark NJ

International Classification:

C07C 4100

US Classification:

568630

Abstract:

The present invention comprises a process for the hydroxyalkylation of cardanol with cyclic organic carbonates in the presence of organic or inorganic catalysts and a novel composition of matter produced by that process. The unique molecular structure of cardanol allows the use of a variety of organic or inorganic basic catalysts, including triethylamine, imidazol, sodium hydroxide and sodium carbonate, in the hydroxyalkylation reaction without forming quantities of undesirable side-products. According to this invention, the final product, monohydroxyalkylcardanyl ether, can be obtained with high yield and high purity. The product has a light color and its color stability is enhanced by replacing the phenol's hydroxyl group with a more stable hydroxyalkoxyl group.

A61K 31445

US Classification:

514278

Abstract:

The present invention is directed to certain piperidines, pyrrolidines, and hexahydro-1H-azepines of the general structural formula: ##STR1## wherein B is selected from: ##STR2## and R. sup. 1, R. sup. 1a, R. sup. 2a, R. sup. 3a, R. sup. 3b, R. sup. 4, R. sup. 4a, R. sup. 4b, R. sup. 4c, R. sup. 5, D, X, Y, n, x and y are as defined herein. These compounds 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 treat physiological or medical conditions characterized by a deficiency in growth hormone secretion, such as short stature in growth hormone deficient children, and to treat medical conditions which are improved by the anabolic effects of growth hormone. Growth hormone releasing compositions containing such compounds as the active ingredient thereof are also disclosed.
