Paragraph 0025; 0026; 0027; 0028, (2016/10/09)
The invention belongs to the technical field of preparation of anti hepatitis C virus drug intermediates and particularly relates to a synthesis method of (1R, 2S)-1-amino-2-vinyl ethyl cyclopropane dicarboxylate. The synthesis method comprises the specific steps that step one, benzaldehyde, glycine ethyl ester hydrochloride, toluene and triethylamine are used as raw materials to be synthesized into a compound 4; step two, the compound 4 and trans-1,4-dibromo butene react in the toluene and sodium ethoxide to prepare a compound 3; step three, the compound 3 and (2S)-2-[(3,5-dichlorobenzoyl peroxide) oxy] propionic acid react in the toluene, and then isopropyl alcohol and hexane are added to obtain a compound 2; step four, the compound 2 reacts with sodium hydroxide in the toluene to obtain a compound (1R, 2S)-1-amino-2-vinyl ethyl cyclopropane dicarboxylate. The synthesis method is simple in operation and suitable for industrialized production, the raw materials are cheap and easy to obtain, and the obtained target product is high in purity and chiral purity.

A practical asymmetric synthesis of the complex fused bis-macrocyclic HCV protease inhibitor MK-6325 (1) is described. Through the combination of a high yielding and low catalyst loading ring-closing metathesis (RCM) to forge the 15-membered macrocycle with an intramolecular sp2-sp3 Suzuki-Miyaura cross-coupling to append the 18-membered macrocycle, multikilogram access to the unique and challenging architecture of MK-6325 (1) has been achieved.

Page/Page column 31, (2013/02/28)
It is an object of the present invention to provide a novel method for producing (1R,2S)/(1S,2R)-1-amino-1-alkoxycarbonyl-2-vinylcyclopropane which is useful as a synthetic intermediate of therapeutic agents for hepatitis C and a synthetic intermediate thereof. According to the present invention, when a trans-2-butene derivative having a leaving group at each of the 1- and 4-positions is reacted with a malonic ester in the presence of a base, a specific amount of an alkali metal alkoxide or an alkali metal hydride is used as the base, and further a specific amount of a malonic ester is used to produce a cyclopropane diester, and further, chiral or achiral 1-amino-1-alkoxy-carbonyl-2-vinylcyclopropane and a salt thereof are synthesized using the cyclopropane diester.
