N,N,N,N-Tetramethylguanidinium acetate as an efficient and reusable ionic liquid catalyst for the one-pot synthesis of dihydropyrrol-2-ones
An extremely facile and efficient procedure which has been developed for the synthesis of dihydropyrrol-2-ones. One-pot four-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of N,N,N,N-tetramethylguanidinium acetate [TMG][Ac] in methanol at ambient temperature provides substituted dihydropyrrol-2-ones in good to high yields. The important aspects of...
متن کاملA green and highly effective protocol for the synthesis of N,N′-alkylidene bisamides using saccharin-N-sulfonic acid
A green and highly effective solvent-free protocol has been reported for the synthesis of N,N′-alkylidene bisamides via the reaction of arylaldehydes (1 eq.) with primary amides (2 eq.) in the presence of saccharin-N-sulfonic acid (SaSA) as a solid-acid catalyst. The mentioned compounds have been obtained in high yields and short reaction times.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولOne-pot synthesis of diverse N,N'-disubstituted guanidines from N-chlorophthalimide, isocyanides and amines via N-phthaloyl-guanidines.
A sequential one-pot approach towards N,N'-disubstituted guanidines from N-chlorophthalimide, isocyanides and amines is reported. This strategy provides straightforward and efficient access to diverse guanidines in yields up to 81% through previously unprecedented N-phthaloylguanidines. This protocol also features wide substrate scope and mild conditions.
