摘要:Improved methods of synthesizing 6-aryl-4-aminopicolinates, such as arylalkyl and alkyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates and arylalkyl and alkyl 4-amino-3-chloro-5-fluoro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates, are described herein. The improved methods include a direct Suzuki coupling step, which eliminates the protection/de-protection steps in the current chemical process, and therefore eliminates or reduces various raw materials, equipment and cycle time as well as modification of other process conditions including use of crude AP, use of ABA-diMe, and varying pH, catalyst concentration, solvent composition, and/or workup procedures. This includes synthesis of 2-aryl-6-aminopyrimidine-4-carboxylates.

摘要:The present invention discloses an improved process for preparation of substantially pure pentamethylene bis(1-(3,4-dimethoxybenzyl)-3,4-dihydro-6,7- dimethoxy-1H-isoquinoline-2-propionate), a compound of formula I and its acid addition salts in good yields. Pentamethylene bis(1-(3,4-dimethoxybenzyl)-3,4- dihydro-6,7-dimethoxy-1H-isoquinoline-2-propionate) or its acid addition salts is the key intermediate for the synthesis of a non-depolarizing neuromuscular-blocking drugs. The process can also be used for the synthesis of various tetrahydroisoquinoline derivatives.

摘要:The present invention discloses a process for preparing ubiquinated peptide conjugates comprising a ubiquitin peptide residue UR attached at its C-terminus to a substrate peptide via a native isopeptide bond, this process comprising combining Native Chemical Ligation (NCL) and solid phase peptide synthesis (SPPS). Further are disclosed ubiquinated peptide conjugates containing a native isopeptide bond, as well as various uses thereof.
