indoline-(thio)urea were designed and prepared using indoline(s) as a new platform and tested as organocatalysts in the Michael and Morita–Baylis–Hillman reactions. Most of the compounds were found to be very active catalysts although they did not promote the enantioselectivity. As agents for the conversion of thiocarbonylcompounds into carbonyl compounds, potentials of PIFA and DDQ were also displayed
摘要 以二氢吲哚为新平台,设计并制备了一系列新型二氢吲哚-(硫)脲,并作为有机催化剂在 Michael 和 Morita-Baylis-Hillman 反应中进行了测试。大多数化合物被发现是非常活跃的催化剂,尽管它们没有提高对映选择性。作为将硫代羰基化合物转化为羰基化合物的试剂,PIFA 和 DDQ 的潜力也得到了展示。此外,DFT 计算使实验观察到的催化剂的非对映选择性合理化。图形概要

A series of potent 5-lipoxygenase-activating protein (FLAP) inhibitors are herein described. SAR studies focused on the discovery of novel alicyclic moieties appended to an indole core to optimize potency, physical properties and off-target activities. Subsequent SAR on the N-benzyl substituent of the indole led to the discovery of compound 39 (AM679) which showed potent inhibition of leukotrienes in human blood and in a rodent bronchoalvelolar lavage (BAL) challenge model.
