Abstract
Four new 1,1-dimethyl-1,2,3,4-tetrahydrophenanthrene derivatives. 1-amino-2 -(1-hydroxy-2-propyl)-8,8-dimethyl-5,6,7,8-tetrahydrophenanthrene-3,4-dione . 2. 3-amino-2-(1-hydroxy-2-propyl)-8,8-dimethyl-5,6,7,8-tetrahydrophenanth rene-1,4-dione. 3. 1,4,9,0-tetramethyl-4,5,9,10,11,12-hexahydro-1H-6-6oax-1 ,3-diaza-dicyclopenta[a,c] phenanthrene 4. 2,4,9,9-tetramethyl-4,5,9,10,11, 12-hexahydro-1,6-dioxa-3-aza-dicyclopenta[a,c]phenanthrene 5. were synthesi zed by reactions of cryptotanshinone 1. a bioactive component from Salvia m iltiorrhiza bunge, with amino compounds.
