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).

标题:Synthesis of pseudopterosin compounds
发明人：COREY ELIAS J
权利人:HARVARD COLLEGE
摘要:The present invention is directed to a new synthetic route to pseudopterosin aglycone (3): n a key intermediate for the synthesis of a group of antiinflammatory natural products including pseudopterosin A (1) and E (2). The pathway of synthesis starts with the abundant and inexpensive (S)-(−)-limonene and its long-known cyclic hydroboration product (4) and leads to the chiral hydroxy ketone (6). Conversion of (6) to (10) followed by a novel aromatic annulation produced (15) which underwent highly diastereoselective cyclization to afford the protected pseudopterosin aglycone (16). The naturally occurring pseudopterosins such as (1) and (2) are readily available from this key intermediate.
