    Chemical resolution of enantiomers of 3,4-dihydropyrimidin-2(1H)-ones using chiral auxiliary approach
    摘要:
    Inherently racemic DHPMs have been resolved using chemical resolution methodology by appending enantiopure chiral auxiliary at N-1 or N-3 position of the DHPMs, leading to the formation of both diastereomers, which were separated chromatographically to obtain both enantiomers (ee upto 99.9%) of DHPMs, after removal of the auxiliary. Absolute configuration of the enantiomers has been assigned. (C) 2012 Elsevier Ltd. All rights reserved.

    摘要:
    甲醇中的镁是化学选择性还原嘧啶2(1 H)-ones的有效试剂。其他可还原的官能团,例如烯胺酯和乌里多羰基的酯和烯烃,不受影响。这构成了通过嘧啶-2(1 H)-one的还原形成Biginelli 3,4-dihydropyrimidin-2(1 H)one的第一个例子。

  • Metalation of Biginelli Compounds. A General Unprecedented Route to C-6 Functionalized 4-Aryl-3,4-dihydropyrimidinones
    作者:Kamaljit Singh、Sukhdeep Singh、Aman Mahajan
    DOI:10.1021/jo050675q
    日期:2005.7.1
    4-Aryl-6-methyl-3,4-dihydro-2(1H)-pyrimidinone esters (DHPMs) readily undergo metalation at the C-6 methyl (vinylogous ester) position on treatment with lithium diisopropylamide at −10 °C. The resulting anion intermediates can be treated with electrophilic reagents to afford functionalized DHPMs that have been chemically elaborated mainly at the C-6 position. Di- and trianion formation is also possible
    在-10°C下用二异丙基氨基锂处理时,4-芳基-6-甲基-3,4-二氢-2(1 H)-嘧啶酮酯(DHPM)易于在C-6甲基(乙烯基酯)位置发生金属化。可以用亲电试剂处理所得的阴离子中间体,以提供功能化的DHPM,该功能化的DHPM主要在C-6位置进行了化学修饰。当用过量当量的碱进行反应时,在乙烯基的甲基和NH位置也可能形成二阴离子和三阴离子。
