Production of methyl levulinate from cellulose: selectivity and mechanism study

An efficient and environmentally friendly catalytic process for the production of methyl levulinate through cellulose alcoholysis was developed. The formation of methyl levulinate follows the sequence: cellulose → methyl glucoside → 5-MMF → methyl levulinate, and Brönsted acid played a key role in its high selectivity.

Acid Catalyzed

A Brønsted acid catalyzed dehydrative arylation of 4-indolylmethanols with indoles has been established, leading to a series of indolyl-substituted triarylmethanes in good to excellent yields (up to 97% yield). In addition, in this Brønsted acid catalyzed dehydration process, the only byproduct was water. Accordingly, this approach can be considered to have high atom economy and to be environmentally friendly. This approach not only provides a useful strategy for the synthesis of structurally diversified indolyl-substituted triarylmethanes, but also represents the first example of a 4-indolylmethanol-involved reaction, which will advance the chemistry of indolylmethanols.
