A mild catalyst system for the synthesis of chiral amino alcohols via asymmetric transfer hydrogenation (ATH) of α-phthalimide ketones has been developed by using a chiral Ru-TsDPEN complex as the catalyst in DMF/MeOH at 40 °C. The reaction exhibits high reaction activity and excellent enantioselectivity where up to 96% yield and 99% ee of the product were obtained.
THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(imidazol-1-ylmeth-yl)isoindole-1,3-dione], C(12)H(9)N(3)O(2), was prepared by reaction of N-(bromo-meth-yl)phthalimide and imidazole in chloro-form solution. The crystal structure is stabilized by weak inter-molecular C-H⋯π inter-actions and inter-molecular π-π inter-actions with centroid-centroid distances in the range 3.6469 (8)-3.8831 (9) Å.
Objective(s): Alzheimer's disease (AD) is a neurodegenerative disorder in elderly patients. Decrease in cholinergic neurotransmission is the main known cause in the pathophysiology of the disease. Improvement and potentiation of the cholinergic system could be beneficial for treatment of the AD. Acetylcholinesterase inhibitors such as donepezil can enhance the duration of action of a...
A Cu-catalyzed aromatic C-H amidation with phthalimide under oxygen as a terminal oxidant without using additional additives has been achieved. This reaction has the broad substrate scope and shows moderate to good yields in most cases. This method is complementary to the previously reported metal-catalyzed C-H amination systems.
Brønsted or Lewis acid assisted activation of an imidogold precatalyst (L-Au-Pht, Pht = phthalimide) offers a superior way to generate cationic gold compared with the commonly used silver-based system. It is also broadly applicable for most common gold-catalyzed reactions. For reactions that require milder conditions, milder acids can be used for optimized efficiency.
تعدادی از الکیل و آریل سولفین ایمیدها از اکسیداسیون سولفین ایمیدهای مربوطه بوسیله آب اکسیژنه در مخلوطی از اسیداستیک و انیدرید استیک تهیه شده اند. اجسام تهیه شده عبارتند از: n-(cyclohexylthio) phthalimide-s-oxide n-(sec-butylthio) phhthalimide-s-oxide n-
Carbonisation of potassium phthalimide (PPI) generates microporous carbons with exceptional gas uptake at 25 °C; 5.2 mmol per g CO 2 @ 1 bar, and methane storage 338 cm 3 (STP) −3 100 bar 100–5 working capacity 249 .
A series of annulated 7-membered oxazepine and 8-membered oxazocine derivatives were synthesized by photoreaction of phthalimide derivatives and an alkene. The antimicrobial activities of the synthesized compounds were evaluated, and compounds 18 and 20 exhibited best antibacterial activity against Gram-positive bacteria. The relationships between structure (especially steric structure) and ant...
