An efficient synthesis of （E）-alken-1,2,3-triboronates form readily available propargylic carbonates is described. The reaction enjoys excellent regio- and E-selectivity and many synthetically useful functional groups can be tolerated. Based on mechanistic studies, a two-step mechanism via 1,2-allenyl boronate intermediate is proposed.

C-H Functionalization with Allenes and Allene Synthesis

中国化学会第十四届全国有机合成化学学术研讨会

作者： shengming ma State Key Laboratory of Organometallic Chemistry Shanghai Institute of Organic Chemistry CAS Department of Chemistry Zhejiang University Fudan University

As we know C-H functionalization has been becoming more and more mature with deeper and deeper understandings of the mechanism, and it will surely become an irreplaceable part of next generation technology for highly efficient synthesis of fundamentally important molecules. In this lecture we will discuss our own advances on C-H functionalization of arenes with allenes or propargylic alcohols/their derivatives.

Carbon Dioxide-Based Transformation

中国化学会·第一届全国二氧化碳资源化利用学术会议

作者： shengming ma Shanghai Institute of Organic Chemistry CAS and Department of Chemistry Zhejiang University and Fudan University

With a growing concern on greenhouse effect, much attention has been paid to the different issues of CO. In this lecture, I would like to show with you some of our efforts on using carbon dioxide for the efficient syntheses stereo-defined alkenes, carboxylic acids, and heterocyclic compounds. Their applications in the synthesis of target molecules including drugs and natural products will also be presented.
