摘要

本研究报道了一种制备具有四级和三级副立体中心的四氢吡喃（THP）衍生物的简便路线。通过原子经济酸催化烯丙基硅烷醇的环化反应，可获得多取代的四氢吡喃，产率高，非对映选择性极佳（95:5）。与传统的氧巯化过程相比，这种方法在产率和立体控制方面都更为有效。

Stereoselective Synthesis of Polysubstituted Tetrahydropyrans by Brønsted Acid‐Mediated Hydroxyalkoxylation of Silylated Alkenols

A convenient route for the preparation of tetrahydropyran (THP) derivatives with a quaternary and tertiary vicinal stereocenters is reported. The atom economy acid‐catalyzed cyclization of allylsilyl alcohols provided polysubstituted tetrahydropyrans in good yields and excellent diastereoselectivities (>95 : 5). In comparison with the traditional oxymercuration procedure, this approach resulted to be more efficient in both yield and stereocontrol.

期刊介绍： Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
