  Grignard Addition to Aldonitrones. Stereochemical Aspects and Application to the Synthesis of C₂-Symmetric Diamino Alcohols and Diamino Diols

  摘要：

  A new example of the stereoselective installation of the amino group at a saturated carbon center via organometallic addition of chiral aldehydes to nitrones is illustrated by the synthesis of 1,3-diamino propanol 1 and 1,4-diamino butandiol 2 units. Three diamino alcohol 1 stereotriads were obtained by stereoselective addition of alkylmagnesium halides (benzyl, cyclohexylmethyl, and metallyl) to the N-benzyl nitrones derived from beta-amino-alpha-hydroxy aldehydes followed by reduction of the resulting N-benzylhydroxylamines. Three 1,4-dibenzyl substituted stereoisomers of type 2 with fixed S configuration at C2 and C3 were prepared by sequential and simultaneous amination in two directions starting from L-threose nitrone and L-tartraldehyde bis-nitrone, respectively. The R,S,S,R isomer obtained by the former route was converted into a seven-membered ring cyclic urea (1,3-diazapin-2-one), i.e., a compound that belongs to a class of nonpeptide HIV-1 protease inhibitors.

  inhibitor DMP 450 has been achieved via W(CO)6/I2-catalyzed carbonylation of diamine intermediates. Carbonylations of related functionalized diamines to derivatives of the DMP 450 core structure were also examined. Selected diamine diol substrates could be converted to the cyclic urea core structure by catalytic carbonylation without protection of the diol functionality.

  HIV蛋白酶抑制剂DMP 450的环状脲核心结构的合成已经通过W（CO）6 / I 2催化的二胺中间体的羰基化而实现。还检查了相关的官能化二胺羰基化为DMP 450核心结构的衍生物。选定的二胺二醇底物可通过催化羰基化转化为环状脲核心结构，而无需保护二醇的功能。
