  Synthesis of Enantiopure 4-Hydroxypipecolate and 4-Hydroxylysine Derivatives from a Common 4,6-Dioxopiperidinecarboxylate Precursor

  摘要：

  tert-Butyl 2-substituted 4,6-dioxo-1-piperidinecarboxylates 4 have been prepared in good yield starting from Boc-Asp-(OBu)-Bu-t and other beta-amino acids. By analogy with chiral tetramic acids, their reduction by NaBH4 in CH2Cl2/AcOH afforded the corresponding cis-4-hydroxy delta-lactams in good yield and stereoselectivity (68-98% de). In the absence of the A(1,3) strain (reduction of 6-substituted 2,4-dioxo-1-piperidines 7), the cis-4-hydroxy isomer was still obtained as the major product but the de values were consistently lower. 4-Hydroxy-6-oxo-1,2-piperidinedicarboxylate 2a, readily accessible from Boc-Asp-OtBu (three steps, 63% overall yield), has proven to be an excellent building block for the synthesis of cis- and trans-4-hydroxypipecolates 17 and 24 (52 and 36% overall yield, respectively) and for the synthesis of a protected 4-hydroxylysine derivative 29 (41% overall yield).

  where the ketone and hydrate forms of the inhibitor 3 predominate in solution. Compound 3 was reduced to the two diastereomeric 4-hydroxy derivatives (4 and 5) and then dehydrated to yield the alkene derivative, 1,2,3,6-tetrahydro-6-oxopyridine-2(S)-carboxylic acid (6). Compounds 4-6 were competitive inhibitors versus thio-dihydroorotate at pH 8.0 with K(i) values of 3.0, 1.6, and 2.3 mM. Dihydroorotase
