摘要

We have designed a new class of non-natural furanosteroids to serve as more chemically stable analogues of the viridins, potent inhibitors of PI-3K. Central to the design is the incorporation of a nitrogen atom into the steroidal ring system to attenuate the activity of the electrophilic 2,4-diacylfuran common to these natural products. In this manuscript, we describe our initial synthetic studies on this ring system and the preparation of key intermediates for analogue generation.
