权利人:TRUSTEES BOSTON COLLEGE; THE TRUSTEES OF BOSTON COLLEGE
摘要:In one aspect, the disclosure relates to a mode of asymmetric induction in radical processes based on sequential combination of enantiodifferentiative H-atom abstraction and stereoretentive radical substitution. Also disclosed is an asymmetric system for stereoselective synthesis of strained 5-membered cyclic sulfamides via radical 1,5-C—H amination of sulfamoyl azides. The disclosed metalloradical system can control the degree and sense of asymmetric induction in the catalytic radical C—H amination in a systematic manner. The disclosed system is applicable to a broad scope of substrates with different types of C(sp 3 )—H bonds and exhibits reactivity and selectivity, providing access to both enantiomers of useful 5-membered cyclic sulfamides in a highly enantioenriched form. Also disclosed are catalysts useful in these processes. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

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:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

摘要:A novel synthesis of salinosporamide A is provided. Salinospoamide A as well as structurally related natural products, omuralide and lactacystin, have been shown to be proteasome inhibitors. Therefore, these compounds as well as analogues of these natural products may be useful in the treatment of proliferative diseases such as cancer, autoimmune diseases, diabetic retinopathy, etc. The invention provides for the synthesis of salinosporamide A as well as analogs thereof using a convenient point for derivatization of the bicyclic core. Pharmaceutical compositions and method of using the inventive compounds are also provided.

摘要:A novel synthesis of scabronines, which are related to a broader class of angularly fused tricyclic diterpenoids known as cyathanes, is provided. Scabronine G, its methyl ester derivative, and other analogs have been shown to have neurotrophic activity. Therefore, these compounds are particularly useful in treating neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, Huntington's diseases, etc. The invention provides for the synthesis of scabronines as well as analogs thereof. Pharmaceutical compositions and method of using the inventive compounds are also provided.
