专利号:US-11548898-B2 优先权日:2017-07-06 标题 :Synthesis of halichondrins 发明人:KISHI YOSHITO; AI YANRAN; YE NING; WANG QIAOYI; YAHATA KENZO; ISO Kentaro; NAINI SANTHOSH REDDY; YAMASHITA SHUJI; LEE JIHOON; OHASHI ISAO; FUKUYAMA TAKASHI 权利人:HARVARD COLLEGE; EISAI R&D MAN CO LTD 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).
专利号:US-7183417-B2 优先权日:2004-04-09 标题:Simple stereocontrolled synthesis of salinosporamide A 发明人:COREY ELIAS J 权利人:HARVARD COLLEGE 摘要:A simple and effective stereocontrolled synthesis of salinosporamide A(1) n nhas been developed which follows the pathway outlined in the FIGURE. The process, the first total synthesis of salinosporamide A, is capable of providing the compound in substantial quantities for further biological studies. In addition to the method of Scheme I, the present invention also includes several novel synthetic intermediate compounds, several intermediate steps of the preferred synthetic process; and the uses of these compounds in the preparation of synthetic derivatives of the compound Salinosporamide A. Salinosporamide A is of special interest as a synthetic target because of its protein in vitro cytotoxic activity against many tumor cell lines (IC 50 values of 10 nM or less).

The invention relates to compounds of general formula (I):wherein:, R1, R2, R3, R4, R5, R6 and Y are as defined herein.The compounds are intermediates in the synthesis of synthetic bile acids which are useful in the treatment of conditions such as liver disease. In addition, the invention relates to a method of synthesizing these intermediates and a method of preparing obeticholic acid and obeticholic acid analogues from the compounds of the invention.
专利号:US-2004018598-A1 优先权日:2000-05-30 标题 :Bio-intermediates for use in the chemical synthesis of polyketides 发明人:SANTI DANIEL; ASHLEY GARY; MYLES DAVID C 摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.
