cis-2-Vinyltetrahydropyran-3-ol (6) is accessible by a selective intramolecular allylboration reaction. Compound 6 was converted into 1,4-dioxa-cis-decaline (4) and cis-syn-cis-perhydrotrioxaanthracene 32; heterocycles with fused tetrahydropyran rings. These ring systems populate predominantly the conformation in which the oxygen atoms are in a gauche arrangement. The tricycle 31 is a rigid derivative
顺式-2-乙烯基四氢吡喃-3-醇(6)可通过选择性分子内烯丙基硼化反应获得。化合物6转化成1,4-二氧杂-顺式-decaline(4)和顺式-顺式-perhydrotrioxaanthracene 32 ; 稠合四氢吡喃环的杂环。这些环系统主要构成氧原子呈薄纱状排列的构象。三轮车31是14-冠-3的刚性衍生物,并且与12-冠-3的情况一样,它与乙腈中的锂离子形成络合物。
