Successful syntheses of the oligonucleotide with higher yield and lesser time have been accomplished employing solid phase synthesis and easy deprotection of Fmoc group with Piperidine.
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).

The described compounds are useful intermediates and may find particular application in the synthesis of compounds containing an octahydrobenzoquinoline moiety (e.g. an octahydrobenzo[g]quinoline moiety), such as quinagolide and its derivatives. Also disclosed is a method for stereoselectively (e.g. enantioselectively) preparing an intermediate used in the existing manufacturing process for the synthesis of quinagolide this intermediate also finding utility in the synthesis of other compounds containing an octahydrobenzo[g]quinoline moiety, in particular those having a substituent at the 3- position on the octahydrobenzo[g]quinoline.

专利号:US-2025026768-A1 优先权日:2023-06-30 标题:Method for the synthesis of axially chiral organoboron compounds 发明人:PING YIFAN; CHE CHI-MING 权利人:LABORATORY FOR SYNTHETIC CHEMISTRY AND CHEMICAL BIOLOGY LTD 摘要:A highly efficient and atroposelective Rh-catalyzed [2+2+2] cycloaddition for the synthesis of axially chiral aryboron compounds is developed. The reactions of diynes and alkynylborons smoothly occur in an atom-economical manner, affording a variety of C—B atropisomers in excellent yields and enantioselectivities. The protocol features mild conditions, broad substrate scope, and good functional tolerance. The obtained C—B atropisomers show powerful synthetic applications in terms of producing novel chiral phosphine ligands.
