determination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...

Cyclopropane Fatty Acid Derivatives: Biosynthesis, Function and Total Synthesis

INTRODUCTION Cyclopropane-containing natural products are very unique owing to their unusual bonding and inherent ring strain (27.5 kcal/mol). 1 This strained ring has been found in naturally occurring terpenes, steroids, amino acids, fatty acids, alkaloids, and nucleic acids. For example, chrysanthemic acid derivatives, produced in plants via isoprenoid pathway are precursors to potent insecti...

The concise synthesis of spiro-cyclopropane compounds via the dearomatization of indole derivatives.

A concise synthesis of spiro-cyclopropane compounds from indole derivatives and sulfur ylides has been developed via a dearomatization strategy. Moreover, the spiro-cyclopropane compounds could be conveniently transformed to rearomatized indole derivatives in the presence of acids.
