摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

摘要:Provided are new nickel./zirconium-mediated coupling reactions useful in the synthesis of ketone-containing compounds, e.g., halichondrin natural products and related molecules. A feature of the present disclosure is the use of a nickel(I) catalyst in tandem with a nickel (II) catalyst in the Ni/Zr-mediated coupling reactions. Without wishing to be bound by any particular theory, the nickel (I) catalyst selectively activates the electrophilic coupling partner (i.e., the compound of Formula (A)), and the nickel(ll) catalyst selectively activates the nucleophilic coupling partner (i.e., a thioester of Formula (B)). This dual catalyst system leads to improved coupling efficiency and eliminates the need for a large excess of one of the coupling partners (i.e., a compound of Formula (A) or (B)).

摘要:Methods of producing N,N-dimethyl sulfamoyl fluoride and related derivatives of the formula F—S(O)2—NR2 (I) by contacting a sulfamoyl nonfluorohalide compound of the formula X—S(O)2—NR2 (II) with anhydrous hydrogen fluoride under conditions sufficient to produce the N,N-dimethyl sulfamoyl fluoride or derivative thereof of Formula I, wherein R in each of Formulas I and II is, independently, a linear or branched alkyl, alkenyl, or alkynyl group containing 1 to 12 carbon atoms, the Rs can be joined to form a cyclic amine with the N, and X is any one of chlorine, bromine, and iodine.

摘要:Methods of producing N,N-branched sulfamoyl fluoride compounds of the formula F-S(O) 2 -NR 2 by contacting bismuth trifluoride with an N,N-branched sulfamoyl nonfluorohalide compound of the formula X-SO 2 NR 2 , wherein X=chlorine (Cl), bromine (Br), or iodine (I), and each R is, independently, a linear or branched alkyl, fluoroalkyl, alkenyl, fluoroalkenyl, alkynyl, or fluoroalkynyl with 1 to 12 carbon atoms, to fluorinate the N,N-branched sulfamoyl nonfluorohalide compound. This is a non-aqueous method, the purity of product is very high, and the desired product can be isolated in quantitative yield. The N,N-branched sulfamoyl fluoride compounds so produced are useful in various applications including as electrolyte solvents and additives in electrochemical devices, such as lithium batteries and capacitors, and in biological fields, among others.

摘要:Improved contaminant removal from alkaline- or alkali-earth metal fluoride crystal growth material can be obtained by coprecipitating an alkaline- or alkali-earth metal fluoride with a scavenging agent during synthesis of the fluoride growth material. The coprecipitation of the alkaline- or alkali-earth metal fluoride and scavenging agent can be performed using at least one of chloride, nitrate, hydroxide and carbonate salts of the alkaline- or alkali-earth metal fluoride and scavenging agent. This provides a more intimate mixture or dispersion of the scavenging agent in solid solution or as a mechanical mixture with the alkaline- or alkali-earth metal fluoride for improved outgassing and fewer trapped impurities, leading to improved radiation hardness and bulk absorption.
