标题 :C-15 phosphonate reagent compositions and methods of synthesizing the same
发明人：BABLER JAMES H
权利人:LOYOLA UNIVERSITY OF CHICAGE
摘要:Allenic phosphonate reagent compositions are described which have the formula: ##STR1## wherein R and R'=C 1 -C 4 alkyl groups, or R, R'=(CH 2 ) n (n=2 or 3) or CH 2 C(CH 3 ) 2 CH 2 !. n Also described are methods for forming such allenic phosphonates from ethynyl-β-ionol, and for converting these allenic compounds to allylic phosphonate compounds which can be used in the synthesis of a variety of biologically-active materials.

标题 :Steroid total synthesis process utilizing a cyanoalkyl A-ring precursor
发明人：COHEN NOAL; ROSENBERGER MICHAEL; SAUCY GABRIEL
权利人:HOFFMANN LA ROCHE
摘要:A multi-step, stereospecific total synthesis of steroids utilizing intermediates having a cyanoalkyl A-ring precursor is disclosed. The initial starting materials for this process are the relatively inexpensive and commercially available reagents γ-butyrolactone and sodium cyanide. The process is suitable for the preparation of racemic or optically active, medicinally valuable steroids, particularly 19-norsteroids. It is a feature of this process that conditions employed during the multiple step synthesis are selected so as to retain the normally labile nitrile group even during hydrogenation and hydrolysis steps. In this manner, it is possible to employ the nitrile group as an A-ring precursor without resorting to protective groups as wasl heretofore found necessary in previous steroid total synthesis processes.
