Studies towards the synthesis of the macrocyclic core of (−)-zampanolide are reported. The synthetic approach features a one-pot reduction/vinylogous aldol reaction for construction of the C15–C20 fragment, an intramolecular silyl-modified Sakurai (ISMS) reaction for construction of the 2,6-cis-disubstituted exo-methylene pyran subunit, and use of an sp2-sp3 Stille reaction for macrocyclization.
Abstract. Fair Value has been taken very seriously around the world since its potential high relevance. China has widely introduced the measurement attributes to the new measurement methods. Large amount of enterprises went bankrupt or suffered capital decrease during financial crisis because of the utilization of Fair Value Measurement, which caused many negative discussions about Fair Value Measurement.

Feasibility analysis is a prerequisite for starting free trade area negotiations. To promote the coordinated development of the regional economy, alleviate the geopolitical risks of the Eurasian continent and maintain national security and social stability, the study on the feasibility of establishing China and Eurasian Economic Union FTA is mainly based on good geographical advantages, historical accumulation, bilateral and multilateral political relations, which obtains a high degree of strategic coordination and economic benefits and potentials. It's found that the Parties have the practical feasibility of establishing FTA in this article. It is a long-term goal of connection cooperation between the Silk Road Economic Belt and Eurasian Economic Union, which is an important part of the strategic layout of China and Eurasian Economic Union to build a FTA network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
