Synthesis method of double different protected amino acids
-
Paragraph 0018, (2019/07/04)
The invention relates to a synthesis method of double different protected amino acids.The technical problems of harsh reaction conditions, inapplicability of production enlarging and the like in an existing synthesis method are mainly solved. According to the technical scheme, the synthesis method of double different protected amino acids comprises the following steps: one of Boc20, Alloc-Cl or Cbz-Osuis added to amino alcohol under the action of an alkaline reagent to obtain a compound 1; the compound 1 reacts with methanesulfonyl chloride or paratoluensulfonyl chloride to obtain an intermediate, then a halide is added into acetone, heating and refluxing are executed to obtain a compound 2; the compound 2 is condensed with diethyl acetamidomalonate under the action of an alkaline agent togenerate a compound 3; the compound 3 is dissolved in alcohol and water, an inorganic base is added, heating, hydrolyzing and decarboxylating are executed to obtain a compound 4; acetylase is added into deionized water to obtain a compound 5 through enzymolysis; amino acid protection is executed, wherein one of Fmoc-Osu, Cbz-OSu, Alloc-Cl or Boc20 is added into thecompound 5 under the action of an alkaline agent to generatea target compound A.

The synthetically useful functionalized 2-substituted piperidines containing a lateral ketone group have been strategically accessed via an organocatalytic enantioselective intramolecular aza-Michael addition of enone carbamates, in which a novel internal substrate combination of the enone moiety as Michael acceptor and the carbamate moiety as Michael donor was revealed in asymmetric bifunctional organocatalysis. This heteroatom conjugate addition, which was realized by using a catalytic chiral Cinchona-based primary-tertiary diamine and an achiral Bronsted acid, mostly proceeded in high yield and good to excellent stereocontrol (up to 99% ee). This reaction provides an alternative catalytic asymmetric method for installing the stereogenic nitrogen-containing carbon center in functionalized 2-substituted piperidines, leading to the development of a straightforward and expeditious synthesis of some naturally occurring bioactive 2-substituted piperidine alkaloids.
