of 3-(4-R-phenyl)propionic acids (R = H, Br, 1-adamantyl) in trifluoroacetic anhydride catalyzed by trifluoromethanesulfonic acid provides a simple and efficient synthesis of 1,3-diketones. Indan-1-ones formed in the first step undergo acylation to give the corresponding 2-(3-phenyl-1-oxopropyl) indan-1-ones as the major products. One-pot synthesis of polysubstituted pyrazoles directly from 3-(4-R-phenyl)propionic
三氟甲磺酸催化的三氟乙酸酐中的3-(4-R-苯基)丙酸(R = H,Br,1-金刚烷基)的自我酰化作用可简单有效地合成1,3-二酮。在第一步中形成的茚满-1-酮进行酰化,得到相应的2-(3-苯基-1-氧丙基)茚满-1-酮作为主要产物。描述了直接从3-(4-R-苯基)丙酸一锅法合成多取代的吡唑。
