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.
专利号:US-6288297-B1 优先权日:1998-10-01 标 题:Process for the preparation of cyclopropylacetylene 发明人:WANG ZHE; YIN JIANGUO; FORTUNAK JOSEPH M; CAMPAGNA SILVIO 权利人:DU PONT PHARM CO 摘要:The present invention relates generally to novel methods for the synthesis of cyclopropylacetylene which is an essential reagent in the asymmetric synthesis of (S)-6-chloro-4-cyclopropylethynyl-4-trifluoromethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one; a useful human immunodeficiency virus (HIV) reverse transcriptase inhibitor. In the process, for example, cyclopropane carboxaldehyde is alkylated to form 1,1,1-trichloro-2-cyclopropyl-ethanol; which in turn is hydroxy protected to form 1,1,1-trichloro-2-cyclopropylethyltosylate; which in turn undergoes elimination to form cyclopropyl acetylene. This improvement provides for high conversion of inexpensive, readily available starting materials into cyclopropylacetylene, high overall yields and can be conducted on an industrial scale.
