Facile and improved synthesis of 4 beta-aminopodophyllotoxin congeners

Bioorg Med Chem Lett. 1998 Nov 3;8(21):3097-100. doi: 10.1016/s0960-894x(98)00570-8.

Abstract

An efficient synthesis of 4 beta-aminopodophyllotoxin from 4 beta-bromopodophyllotoxin using ammonia, and also a facile synthesis of 4 beta-amino-4'-O-demethylpodophyllotoxin from 4 beta-azidopodophyllotoxin by simultaneous azido reduction and selective demethylation at 4'-position employing chlorotrimethylsilane and sodium iodide, has been described. These are potential precursors for the various 4 beta-amino analogs of podophyllotoxin possessing DNA topoisomerase II inhibition activity.
