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。
Compounds of structural formula I are inhibitors of prolylcarboxypeptidase (PrCP). The compounds of the present invention are useful for the prevention and treatment of conditions related to the enzymatic activity of PrCP such as abnormal metabolism, including obesity; diabetes; metabolic syndrome; obesity related disorders; and diabetes related disorders.

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
