Synthesis of proposed structure of rennellianone B: A study on rearrangement of anthraquinonyl propargyl ether toward 2H-pyranoanthraquinone

Rennellianone B was originally reported as a natural 2H-pyranoanthraquinone, isolated from the root of Rennellia elliptica Korth. An efficient synthesis of the proposed structure of rennellianone B was accomplished, starting from alizarin. The key feature of the synthesis involves the Claisen rearrangement of the anthraquinonyl propargyl ether intermediate to provide a 2H-pyranoanthraquinone moiety. In addition, intensive studies on rearrangement reaction conditions of anthraquinonyl propargyl ether toward the 2H-pyranoanthraquinone skeleton were described.
Reaction of 2-acetoxy-3-chloro and 2,3-diacetoxy naphthoquinones with 1,3-dioxy and 1,1,3-trioxy butadienes

Reaction of 2-acetoxy-3-chloro naphthoquinones towards the 1,3-dioxy diene (2) and the 1,1,3-trioxy diene (9) was examined. The competing influence of the acetoxy and chloro substituents was assessed from the regiochemistry of the resulting Diels-Alder ch
