Reported is the first scalable synthesis of?rac-jungermannenones?B and C starting from the commercially available and inexpensive geraniol in 10 and 9 steps, respectively. The unique jungermannenone framework is rapidly assembled by an unprecedented regioselective 1,6-dienyne reductive cyclization reaction which proceeds through a vinyl radical cyclization/allylic radical isomerization mechanism. DFT calculations explain the high regioselectivity observed […]
Abstract: The increase and spread of Gram-negative bacteria resistant to almost all currently available β-lactam antibiotics is a major global health problem. The cause for drug resistance is primarily due to the acquisition of metallo-β-lactamases such as NDM-1. Aspergillomarasmine A (AMA), a fungal natural product, is an inhibitor of NDM-1 and has shown promising in […]
Recently, Prof. Lei has received “Wei Shan Natural Product Synthesis” Award from Chinese Chemical Society. This award was set up in the memory of the late Prof. Wei-Shan Zhou for his remarkable achievements in natural product synthesis, and the goal of this award is to recognize the leading organic chemists in China who has made […]
Our latest Enantioselective Total Synthesis of (?)-Incarviatone A (JACS 2015, 137, 11946-11949) has been highlighted by C&E News. http://cen.acs.org/articles/93/i38/Multi-CH-Functionalizations.html
We have accomplished the first total synthesis of (-)-incarviatone A (1) in 14 steps starting from inexpensive phenylacetic acid. In the course of our synthetic studies, we have developed a scalable and sequential C-H functionalization process for the rapid assembly of the highly functionalized indane skeleton. More interestingly, we have also identified a striking biomimetic […]

We report the first scalable total synthesis of tetracyclic diterpenoid jungermannenones B and C

The unique jungermannenone framework is rapidly assembled by an unprecedented regioselective 1,6-dienyne reductive cyclization reaction which proceeds through a vinyl radical cyclization/allylic radical isomerization mechanism.
