Abstract
Intramolecular Lewis acid-catalyzed cyclization reactions of steroid a ryliminium salts 4a-e obtained from the secoestrone aldehyde 2 yield e ither the tetrahydroquinoline derivatives of estrone methyl ether 8a-d or the N-arylamino-D-homosteroids 7a-f, depending on the nature of th e substituent R at the aniline moiety in 4.
