گیاهان juniperus excelsa m.beib. ,juniperus communis l. و juniperus sabina l. از گونههای دارویی با ارزش و معطر متعلق به جنس سروکوهی و راسته مخروطیان میباشند که در ارتفاعات رشته کوه البرز پراکندگی دارند. هدف از این پژوهش، شناسایی و مقایسه اجزای تشکیل دهنده اسانس میوه ها و سرشاخههای هوایی این گیاهان میباشد. در این تحقیق میوه و سرشاخههای سه گونه فوق در مرداد سال 1390 از منطقه هزار جریب بهشهر...
Herein, we report a copper-catalyzed C-O cross-coupling of N-methoxy amides and arylboronic acids for the synthesis aryl-N-methoxy arylimides. The fully selective O-arylation is found to be greatly prompted by inexpensive commercially available CuI. reaction conditions tolerate variety functional groups promote different reactivities depending on electronic steric properties distorted substrates.
Well-dispersed palladium(0) nanoparticles with small and narrow size distributions were synthesized conveniently on a graphene oxide (GO) surface. The GO-supported nano-Pd(0) was found to be a highly efficient and recyclable catalyst for the carbonylative cross-coupling reaction between arylboronic acids and aryl and carboranyl iodides, respectively. Benzophenone and a series of carboranylaryl ...
Cinnamaldehyde derivatives were synthesized in good to excellent yields in one step by a mild and selective, base-free palladium(II)-catalyzed oxidative Heck reaction starting from acrolein and various arylboronic acids. Prepared α,β-unsaturated aldehydes were used for synthesis of novel α-aryl substituted fosmidomycin analogues, which were evaluated for their inhibition of Mycobacterium tuberc...
