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 preparation method of thiol derivative as side chain intermediate for synthesis of carbapenem derivative. The method is starting with trans-4-hydroxy-L-proline derivative as starting material, following by one-pot method that 2-carbonyl group is protected, 4-hydroxy is protected and 2-postion is substituted to obtain 2-amide proline derivative, then 4-postion is substituted and 4-postion is hydrolyzed in the presence of base to obtain thiol side chain derivative as important intermediate for Meropenem. The present method is simple, without separating intermediates, with high yield and easy to operate and has advantages over the prior patent methods. It is suitable for industrial production.
