标题:Photolysis Ofn-Nitrosamines In Neutral Media
摘要:Abstractthe Photolysis Of N‐nitrosamines In Solutions Of Acetonitrile Follows A First‐order Reaction With Respect To The Concentration Of Nitrosamine. Quantum Yields Are Very Low (~ 0.1) And Depend On The Concentration Of Nitrosamine,With The Observation Of A Linear Correlation Between The Reciprocal Of Quantum Yield And The Reciprocal Of Nitrosamine Concentration. For All The Nitrosamines Studied,The Final Product Of The Photolysis Appears To Be Unique,Alkylidenimine,Which In The Case Of Nitroso Methyl Benzyl Amine Undergoes A Relatively Rapid Hydrolysis,Giving Rise To Benzaldehyde,Following Second Order Kinetics. A Provisional Model Consistent With The Experimental Results Obtained In This Work Is Proposed. © 1993 John Wiley & Sons,Inc.

标 题:Preparation and use of (2-butene-1,4-diyl)magnesium complexes in organic synthesis

摘要:The magnesium complexes of cyclic hydrocarbons containing conjugated dienes, such as 1,2-dimethylenecycloalkanes, and 1,3-butadienes, are readily prepared in high yields using highly reactive magnesium. Reactions of these (2-butene-1,4 diyl)magnesium reagents with electrophiles such as dibromoalkanes, alkylditosylates, alkylditriflates, bromoalkylnitriles, esters, or amides serve as a convenient method for synthesizing carbocyclic systems. Significantly, carbocycles prepared by this method contain functional groups such as the exocyclic double bond or a keto group in one of the rings which could be used for further elaboration of these molecules. Furthermore, fused bicyclic systems containing a substituted five-membered ring can be conveniently prepared at high temperatures by the reactions of (2-butene-1,4-diyl)magnesium complexes with carboxylic esters or acid halides whereas low temperatures lead to regioselective synthesis of β,γ-unsaturated ketones. Additionally, γ-lactones, including spiro γ-lactones, can be easily prepared in a one pot synthesis from the reaction of (2-butene-1,4-diyl)magnesium complexes with a ketone or aldehyde and carbon dioxide. Also, δ-lactones can be easily prepared in a one pot synthesis from the reaction of (2-butene-1,4-diyl)magnesium complexes with epoxides followed by reaction with CO 2 . Use of α-hydroxy epoxides without the addition of CO 2 leads to the synthesis of vicinal diols. Chiral epoxides lead to chiral alcohols.

摘要:Polypeptides of formula (I): n nwherein R 1 and R 2 are substituents independently selected from substituted and un-substituted alkyl groups and substituted and un-substituted aryl groups, and n is an integer greater than or equal to 2. Synthesis methods are also provided that do not use amino acids as starting materials, but instead employ imines and carbon monoxide as monomers that undergo transition metal-catalyzed alternating copolymerization to directly provide polypeptides using an acylcobalt catalyst with the following structural formula:n n nwherein R is selected from the group consisting of alkyl, phenyl, and substituted phenyl groups.
