A Simple and Convenient Method for Synthesis of Artemisinin Dimer through Aliphatic Nitro Compounds

A simple way of synthesis of artemisinin dimer using nitro aliphatic compounds is reported. Herein, few artemisinin monomers and dimers have been synthesized with the help of linker nitroalkanes using iron catalyst supported on polymer (Fe/SBA-15). The synthesized artemisinin shows good anticancer and antimalarial activities

A One-Pot Approach to 2-(N-Substituted Amino)-1,4-naphthoquinones with Use of Nitro Compounds and 1,4-Naphthoquinones in Water

A one-pot synthesis of 2-(N-substituted amino)-1,4-naphthoquinones from 1,4-naphthoquinones and nitro compounds in water has been developed. This method features mild reaction conditions and provides aromatic nitro compounds with various functional groups such as halogens, methylthio, ester, amide, even allyl, propargyl, and heterocycles, as well as aliphatic nitro compounds that are well tolerated. This method can be scaled up and we conducted further transformation of the obtained 2-(N-substituted amino)-1,4-naphthoquinones to synthesize carbazolequinone derivatives.

Tandem double acylation/[3,3]-rearrangement of aliphatic nitro compounds: a route to α-oxygenated oxime derivatives

A novel efficient regioselective method for the carbon chain activation of aliphatic nitro compounds is described using a tandem double acylation/[3,3]-rearrangement sequence.
