标 题 :Preparation of amides from an acid and amine for intermediates in the synthesis of morphinans

摘要:The present invention is directed to processes for the synthesis of morphinans. In particular, a process for coupling a carboxylic acid compound with an amine compound to form an amide product that can then be isolated or the crude amide product can be cyclized to form a 3,4-dihydroisoquinoline. In one embodiment, the carboxylic acid contains a phenol moiety protected with a labile protecting group. The protected phenol reduces reaction times, simplifies work-up of the product, and reduces the amount of cyclizing agent, POCl 3 that is necessary to form the 3,4-dihydroisoquinoline.

标题:Solid phase synthesis of immunosuppressive agents
发明人：RICH DANIEL H; RAMAN PRAKASH; ANGELL YVONNE M
权利人:WISCONSIN ALUMNI RES FOUND
摘要:The present invention relates generally to cyclosporin analogs, and more paritcularly to methods for the solid-phase synthesis and on-resin cyclization of cyclosporin analogs. Methods are described for the on-resin cyclization of sterically hindered compounds synthesized through solid phase synthesis techniques. The methods utilize solvent, temperature, and washing conditions that allow the efficient on-resin cyclization of compounds like analogs of cyclosporin A.

摘要:The present invention relates to novel chemical compounds, to methods for synthesis of such compounds, and to the use of these novel compounds in the synthesis of other chemical compounds that, inter alia, may be used in the treatment of sexual dysfunction, and for eliciting enhancing effects on sexual behavior. The invention also relates to remarkable biological properties of the novel compounds in their capacity of inducing aggressive behavior.
