  Separation of enantiomers of 4-aryldihydropyrimidines by direct enantioselective HPLC. A critical comparison of chiral stationary phases

  摘要：

  The separation of the enantiomers of 29 racemic 4-aryldihydropyrimidine-5-carboxylates (DHPMs), aza-analogs of nifedipine-type dihydropyridine calcium channel modulators, was evaluated in direct enantioselective HPLC, employing the following commercially available chiral stationary phases (CSPs): Chiralcel OD-H, ChiraDex, Chirobiotic V and T, and Whelk-O1. In addition, a 1,2-diphenyl-1,2-diaminoethane based CSP and two quinine carbamate based chiral ion exchangers were also employed. For all 29 DHPMs separation of individual enantiomers could be achieved with at least one CSP with alpha-values ranging from 1.10 to 8.67. (C) 1997 Elsevier Science Ltd.

• Metalation of Biginelli Compounds. A General Unprecedented Route to C-6 Functionalized 4-Aryl-3,4-dihydropyrimidinones

  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。
