give γ‐ and δ‐lactams has been studied in the presence of chiral ligands. Ligand (R)‐3,5‐tBu‐MeOBIPHEP (MeOBIPHEP=6,6’‐dimethoxybiphenyl‐2,2‐diyl)bis(diphenylphosphine)) afforded the best results and allowed the cyclization reactions to take place in up to 94:6 enantiomeric ratio. A model Pd–allyl complex has been prepared and studied through NMR spectroscopic analysis, which provided insight into the
在手性配体存在下,对钯催化的不饱和酰胺的分子内烯丙基烷基化反应生成γ-和δ-内酰胺进行了研究。配体(R)-3,5- t Bu-MeOBIPHEP(MeOBIPHEP = 6,6'-二甲氧基联苯-2-2,2-二基)双(二苯基膦))提供了最佳结果,并使环化反应可在多达94个条件下进行:6对映体比率。制备了钯-烯丙基复合物模型,并通过NMR光谱分析进行了研究,该分析提供了对观察到的对映体比率负责的过程的见解。DFT研究用于表征非对映异构反应途径。计算出的能量差与实验观察到的对映体比率非常吻合。

The present invention relates to: a cyclohexene derivative; a preparation method thereof; and a pharmaceutical composition for preventing or treating metabolic disease comprising the same as an active ingredient. The cyclohexene derivative according to the present invention increases the intracellular activity of cyclic adenosine monophosphate (cAMP) by activating G protein-coupled receptor 119 (GPR-119) and simultaneously exhibits weight loss and hypoglycemic effects by inducing the release of glucagon-like peptide-1 (GLP-1), which is a neuroendocrine protein, and thus can be useful as a pharmaceutical composition for preventing or treating metabolic diseases such as obesity, type 1 diabetes, type 2 diabetes, inadequate glucose tolerance, insulin resistance, hyperglycemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, dyslipidemia and syndrome X.
