peptidomimetics serve as biologically active compounds or as intermediates for other peptidyl isosteres. We developed a chemoenzymatic stereoselective approach to optically active γ-hydroxy sulfones to be assembled into peptidyl olefins by the Julia reaction. Key enzymatic hydrolysis of prochiral diesters to the corresponding hydroxy esters introduces optical activity. The sequence of the subsequent
肽基烯烃肽模拟物用作生物活性化合物或用作其他肽基等排体的中间体。我们开发了一种化学酶立体选择性方法,用于通过 Julia 反应将光学活性 γ-羟基砜组装成肽基烯烃。前手性二酯到相应羟基酯的关键酶水解引入了光学活性。随后的化学反应顺序,无论是保护-水解-功能化还是功能化-水解-保护,决定了最终砜结构单元的绝对立体化学。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008 )
