Reaction of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride with ammonia.
The conversion of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride (I) to L-2-acetylamino-2-carbomethoxyethanesulfonamide (II) proceeds with considerable variability in yield We therefore investigated the nature of the by-product (s) of this reaction in order to prepare II in consistently high yields and with reproducible physical data. Compound II [m. p. 145°, [a] 54 2 8 ° (c 2, 95% ethan...
متن کاملApplication of Green Procedure for the Synthesis of Substituted Pyrroles: Multi-component Reaction of Oxalyl Chloride
A novel, convenient and efficient approach to synthesis of pyrrole derivatives via the reaction of primary amines, alkyl propiolates and oxalyl chloride is described. The method offers several advantages including high yields of products and performing reaction in water as the solvent.
متن کاملReaction of diazoalkanes with 1-substituted 2, 4-dioxopyrimidines. Formation of O2, N-3 and O4-alkyl products.
In non-aqueous solution, diazomethane and diazoethane react with the O2, O4 and N-3 sites of uridine, thymidine, 1-methyluracil and 1-methylthymine. Diazoethane has a higher affinity for alkylating oxygens than does diazomethane. The relative ratio of O2:O4:N-3 methyl products is 1:2:16 and of ethyl products the ratio is 1:1:2. When the diazoethane reaction is performed in neutral buffered solu...
متن کاملSynthesis of MgO Nanoparticales and Identificationof Their Destructive Reaction Products by 2-Chloroethyl Ethyl Sulfide
Nanocrystalline magnesium oxides were prepared by sol–gel method and were characterized by X-ray diffraction, N2-BET, SEM and infrared spectroscopy techniques. The results confirmed the formation of Nano- MgO materials with crystallite size in range of 5-20 nm and surface areas of 336-556m2/g. The product has been tested as destructive adsorbent for the decontamination of (2-chloroethyl) et...
متن کاملThe synthesis of 5- picrylamino-1, 2, 3, 4-tetrazole (PAT) from the reaction of 5-amino-1, 2, 3, 4-tetrazole with picryl chloride in different temperature conditions, the DFT method
In this article, synthesis of the explosive synthesis of 5- picrylamino-1, 2, 3, 4-tetrazole (PAT) from the reaction of 5-amino-1, 2, 3, 4-tetrazole with picryl chloride in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then th...
