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: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.

标题 :Synthesis of c5-substituted tetracyclines, uses thereof, and intermediates thereto

摘要:The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides more efficient routes for preparing the enone intermediate and allows for a wide variety of substituents at position 5 of the tetracycline ring system.

摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.
