Synthetic Approaches to the Ring System of Nicandra (Benzenoid Ring D) Steroids
Blumbach, J.,Hammond, D. A.,Whiting, D. A.
, p. 261 - 268 (2007/10/02)
The androstenolone derivative (5) has been converted into the aromatic ring D steroid (39), with the C/D system of the novel natural steroid Nic-10.The route employs the seco-acid (15) which is cyclised to the D-enone (16).Selective D-aromatisation was en
BIOGENETICALLY-INSPIRED AROMATISATION OF A STEROID D-RING
Blumbach, J.,Hammond, D. A.,Whiting, D. A.
, p. 3949 - 3952 (2007/10/02)
The androstenolone derivative (4) has been converted to the aromatic ring D ketone (16), in which the former C/D angular methyl is incorporated into the new D-ring, as in biosynthesis of Nicandra steroids.
