Abstract
Methods for producing novel artemisinin analogs and artemisinin dimers having antimalarial, antiproliferative and antitumor activities are described herein. These novel artemisinin analogs and artemisinin dimers have the following structure ##STR1## or diastereomers thereof, having antimalarial, and antiproliferative and antitumor activities wherein, the monomers of the present invention are formed when n is 1 and R is alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, alkenyl, alkynyl, aryl or heteroaryl. The dimers of the present invention are formed when n is 2 and R is a linker including, but not limited to, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, alkenyl, alkynyl, aryl or heteroaryl.
