Efficient Synthesis of a Novel Estrone- Talaromycin Hybrid Natural Product

Abstract

Numerous pharmacologically interesting compounds are available by the synthesis of hybrid natural products. Thus, for instance, the estrone-talaromycin hybrid 2, which is synthesized in a few steps from the estrone derivative 1 by a sequence in which a hetero-Diels-Alder reaction is the key step, exhibits notable cytotoxic activity.
