پروفیسر محمد عمر الدین

پروفیسر محمد عمرالدین
افسوس ہے پچھلے دنوں پروفیسر محمد عمر الدین کا ۶۲ برس کی عمر میں انتقال علی گڑھ میں ہوگیا،اوریہیں دفن ہوئے۔ مرحوم علی گڑھ یونیورسٹی میں ۲۴ء میں داخل ہوئے تھے، اُس وقت سے دمِ آخرتک اُن کا رشتہ اس درس گاہ سے منقطع نہیں ہوا۔ انھوں نے تعلیم یہیں مکمل کی، پھر یہیں لکچرر، ریڈر، پروفیسر اورصدر شعبۂ فلاسفی ونفسیات، وارڈن، اور پروووسٹ اورخداجانے کیاکیا ہوئے۔انھوں نے یونیورسٹی میں بڑے بڑے اتار چڑھاؤ اورانقلابات دیکھے تھے،اوراب آخر میں خود انقلاباتِ زمانہ کی عبرت انگیز تصویربن کررہ گئے تھے۔اسلامی فلسفہ اُن کا خاص مضمون تھا، امام غزالی ؒ کے فلسفۂ اخلاق پرانگریزی میں اُن کی ضخیم کتاب چند سال ہوئے یونیورسٹی کی طرف سے شائع ہوئی ہے۔بلاکے ذہین، بہترین منتظم،بے نفس وبے ریا، مجّسم خلوص، پیکرِ وضع داری، اور نہایت سادہ اوربے تکلّف! راقم الحروف سے دیرینہ اور بڑے مخلصانہ تعلقات تھے، یونیورسٹی سے ملازمت کے تعلق کے اعتبارسے مرحوم اس چمن کی پرانی بہار کی آخری نشانی تھے۔ ’’خدا بخشے بہت سی خوبیاں تھیں مرنے والے میں‘‘۔ [ستمبر ۱۹۶۴ء]

برصغیر میں محدثین کی خدمات حدیث: تاریخی و تجزیاتی جائزہ

After the Prophet r the Muslims all over the world associate themselves with him by following his pious deeds and acting upon his sayings (Hadith). The Muslims of the sub-continent have been very zealous in this respect and have done great job in this regard. In the subcontinent, the sayings of the Holy Prophet reached with Islam during the era of pious caliphs. In those days, according to some traditions, 25 companions of the Holy Prophet ﷺ Sahaba (R. A) and 42 Tabe-ien (those who had seen the Sahaba R. A i-e their successors) came to India and preached Islam. This preaching was continued by later Muslims and the rulers like Mohammad Bin Qasim and Mehmood Ghaznavi. The services of great Muhaddeseen (narrators and illustrators of the sayings of the Holy Prophet r like Musa Bin Yaqoob, Yazid Bin Abi Kabsha, Abu Musa Israeel Bin Musa and Abu Hafs Rabi Bin Sabih are note worthy. They provided local people the knowledge of Hadith. These scholars earned fame and prestige by their great works in this field. Shah Waliuallah wrote Mussffa and Maswwa, in subcontinent there are great many institutions like Jamia Salfiya Faisalabad, Jamia Ashrafia Lahore, Jamia Naeemia Lahore, Khair- ul-Madaras Multan, Jamia Mohammadia Gujranwala, Dar-ul-Hadith Delhi and Jamia Salfiya Banaras to teach the knowledge of Hadith.

Synthesis of Novel Heterocyclic Compounds

The present dissertation entitled “Synthesis of Novel Heterocyclic Compounds” is comprised of two parts. Part A describes the synthesis of Azaborines. In Part A the synthesis of Azaborines is classified into two classes. (a) 1, 3, 2 benzodiazaborininones (carbonyl containing, boron-based heterocyclic scaffolds) (68-89). In the synthesis of 1, 3, 2 benzodiazaborininones, anthranilamide reacted with different commonly available potassium organitriflouroborates using a fluorophile (BF3NH2Et) with efficient methodology.

These were obtained by reacting N-benzyl-2-vinylaniline with potassium organotrifouroborates in the presence of SiCl4 and Et3N. 2-Ethynyl-1,2-dihydroazaborinines (96-97, b2) were synthesized by using the same methodology where 2-vinylaniline was used with different commercially available potassium organotriflouroborates. All the products synthesized were charecterzied by FT-IR, 1H-NMR, 13C-NMR, 11B-NMR, HRMS. The results obtained confirmed the formation of desired product.

The 2, 4- disubstituted quinolines were synthesized using a Povarov related reaction using indium chloride as a catalyst. Two classes of 2,4 di-substituted quinolines were prepared. (c) Quinoline isoindolindiones (187-193) products were synthesized in two steps.The First step involved Schiff base synthesis while second step involved condensation of Schiff bases with N-propargylphthalimide.

These compounds were prepared by reacting aldehydes, 1-naphthyl amine with N-propargylphthalimide in presence of indium chloride catalyst. All these compounds were characterized through FT-IR, 1H-NMR and 13C-NMR. Along with N-propargylphthalimide, another alkyne, 1- nitro-4-(prop-2-ynyloxy)benzene was used under the same conditions. A reaction was attempted where 1-nitro-4-(prop-2-ynyloxy)benzene was reacted with benzo[c][1,2,5]thiadiazol-5-amine and different aldehydes, but the product isolated was not the desired one.
