  Synthesis of chiral diamines using novel 2-trichloromethyloxazolidin-4-one precursors derived from 5-oxo-proline and proline

  摘要：

  Efficient syntheses of chiral vicinal diamines derived from (S)-oxo-proline and (S)-proline are described. The novel diastereomerically pure precursor (2R,5S)-2-trichloromethyl-1-aza-3-oxabicyclo-[3.3.0]-octan-4,8-dione 3 and its enantiomer are readily available by reaction of the inexpensive enantiomers of 5-oxo-proline with chloral. Compound 3 reacts with primary and secondary amines to afford the 5-oxo-prolylamides 4 in quantitative yield. In contrast, the (S)-proline-derived precursor (2R,5S)-2-trichloromethyl-1-aza-3-oxabicyclo[3.3.0]octan-4-one 6 gave (S)-N-formylprolylamides 9 and/or (S)-prolylamides 8 depending on the reaction conditions. Upon reduction with LiAlH4, amides 4 and 9 afforded the proline-derived (S)-2-(alkylaminomethyl)pyrrolidines 1 and (S)-N- methyl-2-(alkylaminomethyl)-pyrrolidines 5 in 70-90% yields.

  The invention provides pyrazolo[3,4-b]pyridine compounds of formula (I) having a —C(O)—NH—C(R 4 )(R 5 )-aryl substituent at the 5-position of the pyrazolo[3,4-b]pyridine ring system wherein at least one of R 4 and R 5 is not a hydrogen atom (H) compound or a salt thereof: wherein Ar has the sub-formula (x) or (z). These compounds are useful as inhibitors of PDE4.

  本发明提供了式(I)的吡唑并[3,4-b]吡啶化合物，其在吡唑并[3,4-b]吡啶环系的5位具有—C(O)—NH—C(R4)(R5)-芳基取代基，其中R4和R5中至少有一个不是氢原子（H）化合物或其盐：其中Ar具有亚式（x）或（z）。这些化合物可用作PDE4的抑制剂。
