First total synthesis of (-)-auranomide C and its derivatives
Sorra, Kumaraswamy,Mukkanti,Pusuluri, Srinivas
, p. 189 - 194 (2014)
The first total synthesis of (-)-auranomide C has been achieved. The short synthetic strategy involves a reductive dehydrocyclization and the nucleophilic ring opening of a fused γ-lactam. The route allows for ease in synthesizing diverse derivatives in the side chain of the natural product.
