Novel chiral lipoxygenase substrates: design and synthesis. Part 2
摘要:
A series of novel lipoxygenase substrates carrying a spacing modifier with a non-ionic hydroxyl terminus have been synthesized in an enantioselective fashion. One of the methylene hydrogens (flanked by the cis,cis-pentadienyl moiety) is replaced by alkyl, aryl and hydroxyl groups. The key steps in the synthesis involved enzymatic transesterification of 1,3-propanediol derivatives and two consecutive cis-selective Wittig olefinations. (C) 2002 Elsevier Science Ltd.

Sulfone analogues of previously prepared tetrahydropyranoid podand receptors bind C-terminal amides and esters of alpha-amino acids with enantioselectivity as high as 80% ee. X-ray structures of the free receptor and several of its complexes are reported.
