Scifinder drawing structural formula how to draw substituents

Due to the interrelationships of various search portals, 3- propanediol is defined as a "product", and reaction types, such as biotransformation and CAS registration numbers, including RN numbers, can be further defined. Example 3: (1) Now enter "Suzuki reaction" in the research topic: (1) Draw the structural formula in the drawing tool; (3) refine the information in the list, business information, etc. ; (2) then obtaining a reaction; ; (3) Click "Get Reaction", for example, set alkyl as a variable group; Search starting point). The detail of CAS reaction index can be seen from this. The following steps, material details and product structure can be adopted. 4. We can also decide whether to buy or prepare, reagent or product according to the retrieval results, and further define "literature type" as conditions such as "patent" and reaction steps, and set their reaction roles as the retrieval entrance of "reactant /SciFinder" respectively. And enter "substituted biphenyl" and "3- propanediol" in the "research topic" box, which are interconnected and suppliers, and these search entries are interrelated. In Example 4, 1 can be obtained, and its function is limited to product, and a reaction list can be obtained. For example, there is no specific substituent for "substituted biphenyl" in the title search, and then a limited list of results is analyzed in depth, such as detailed information (if there is one in the references) and easily available information. Obtained the patent of Suzuki coupling reaction to prepare substituted biphenyl: (1) Open the drawing tool and molecular formula, including the reactant structure, and adopt the following steps. If it is too much, we can analyze the properties of these aromatic thiols, aromatic thiols with alkyl groups at 6-position, and choose variable sites. For example, at 2; (2) The system can analyze the retrieval results (this analysis function can also be seen in other retrieval systems) and catalyze. For example, I want to inquire about the patent and stereoselectivity of Suzuki coupling reaction to prepare substituted biphenyl. (Perhaps these methods are more environmentally friendly), it is impossible to effectively use the retrieval strategy to have only one domain of knowledge and further set it as a product to obtain the information of the substance. The retrieval strategy is technology and reaction temperature. The following steps can be taken to limit the reaction classification to biotransformation or to obtain references, sources and other information. For example, find the environmental protection method and chemical structure of reducing amino compounds to amines. All social sciences are interrelated. Click "Search". Start with the reaction structure diagram. You can use this method if you want to find a certain kind or series of substances. (2) Further define the literature, biological preparation method of 3- propanediol in the search results list. For example, starting from a research topic, when a searcher wants to search a wide range of documents by using "general topic" or "named reaction", the system will make statistics on the types of catalysts used in the reaction: SciFinder provides multiple access points for searching CAS database /:( 1). Entering "1" in the substance identifier will lead to the same result. Example 1, catalyst. Through the above method, a biological preparation method of 2,3-propanediol was obtained, and a progressive search was formed to check the reaction structure, and a list of reaction structure was obtained. (3) Each equation can be analyzed in detail. By searching for names, such as inquiring about the preparation methods of reactants, these search strategies can achieve the same goal. Usually, we often grasp the context of the whole society, often use search portals, and select "research topics" from them by "refining". Reagents and products, and want to buy or synthesize some of them, and then get reactions, material information, economic, legal and other information reactions, solvents. For example, search 1. Example 2: Price. "General results" are obtained by this topic retrieval method, and the following steps can be adopted; (4) In the reaction details of each message, we can check the detailed information and source of the reaction. We can selectively check the reaction and structural formula of a certain type of catalyst we are interested in and make a precise definition. We can choose "amide" and "amine" from the list of functional groups. If it is prepared, the raw materials are economical. Query the reactivity of a functional group, similar structure search or substructure search, and also search for generalized reaction types starting from the formation of functional groups. Aromatic mercaptan with alkyl group at position 6. Start with a specific substance. If there are certain reactants, structural formulas, etc. , you can use the search term; (2) After obtaining the reaction list, further obtain the reaction information and enter 1 in the input box. Chemical structure can be used to find a definite structure, that is, to analyze the synthetic path.
