The reaction of 4/5-carbonyl-cycloalkenone 1 or its achiral isomer 1′ with organoboronicacid 2 in the presence of a chiral diene (S,S)-Fc-tfb-rhodium catalyst gave disubstituted trans-cycloalkanone 3 with high diastereo- and enantioselectivity. This highly efficient dynamic kinetic resolution is achieved by fast racemization of 1 through the formation of a dienolate followed by kinetic resolution
4/5-羰基-环烯酮1或其非手性异构体1'与有机硼酸2在手性二烯( S , S )-Fc-tfb-铑催化剂存在下反应,得到具有高非对映异构体的二取代反式环烷酮3。和对映选择性。这种高效的动态动力学拆分是通过形成二烯醇化物使1快速外消旋化,然后使用手性催化剂进行动力学拆分来实现的。该实用性通过合成 (−)-大麻二酚途中的关键中间体得到证明。

<i>D</i><sub>3<i>h</i></sub>-Symmetrical Hydrogen-Bonding Unit as a Saccharide Recognition and Self-Assembling Module
A D-3h-symmetrical triresorcinol module 1,3,5-tris(2,6-dihydroxy-4-pentylphenyl)benzene (3) was investigated in terms of its hydrogen-bonding ability for glycoside recognition and self-association. When 3 was treated with glycoside, corresponding changes were induced in H-1 NMR, UV, and CD spectra. The titration experiments indicated the participation of not only a 1:1 but also a 1:2 association of a glucosamine derivative guest. Self-association of 3 caused gelation with CDCl3, and was studied by H-1 NMR and X-ray analysis.
