    烯丙基-B(pin)化合物对酮和α-酮酸酯的实用且广泛适用的催化对映选择性加成
    摘要:
    开发了一套广泛适用的方法,用于将易于处理的烯丙基-B(pin)(pin = pinacolato)化合物有效催化加成到酮和无环α-酮酸酯中。因此,可以以60至> 98%的产率和高达99:1的对映体比例获得各种各样的叔醇。这一发展的核心是合理改变小分子氨基酚基催化剂的结构。明显地,对于酮,增加催化剂部分的尺寸(tBu至SiPh 3)导致更高的对映选择性。另一方面,对于α-酮酸酯,不仅如此,因为Me取代会导致对映选择性大大提高,而且选择性的意义也相反。

    Mesoporous aluminosilicate-catalyzed allylation of carbonyl compounds and acetals
    摘要:
    A mesoporous aluminosilicate (Al-MCM-41) was found to be an effective heterogeneous catalyst for the reaction of both carbonyl compounds and acetals with allylsilanes to afford the corresponding homoallyl silyl ethers and homoallyl alkyl ethers, respectively. Both the mesoporous structure and the presence of aluminum moiety were indispensable for the high catalytic activity of Al-MCM-41. Moreover, Al-MCM-41 could catalyze the reaction of acetals chemoselectively in the presence of the corresponding carbonyl compounds. The solid acid catalyst Al-MCM-41 could be recovered easily by filtration and could be reused three times without a significant loss of catalytic activity. (C) 2011 Elsevier Ltd. All rights reserved.

    Photoinduced electron transfer (PET) reactions promoted by 2-aryl substituted 1,3-dimethylbenzimidazolines (Ar-DMBIH) were investigated. Excited states of Ar-DMBIH, formed by irradiation using light above 360 nm, initiate PET reductions of various organic substrates, including transformations of epoxy ketones to aldols, free radical rearrangements such as the Dowd-Beckwith ring-expansion and 5-exo
    研究了由2-芳基取代的1,3-二甲基苯并咪唑啉(Ar-DMBIH)促进的光诱导电子转移(PET)反应。通过使用360 nm以上的光进行辐照而形成的Ar-DMBIH激发态,可引发PET还原各种有机底物,包括将环氧酮转变为羟醛,自由基重排(如Dowd-Beckwith环扩环和5-外己烯基环化) ,对N脱保护-磺酰基吲哚和酰基甲酸酯的烯丙基化。在这些方法中,具有1-萘基,2-萘基,1-吡啶基和9-蒽取代基的Ar-DMBIH在形式上起两个电子和一个质子供体的作用,而被羟基萘基取代的衍生物充当两个电子和两个质子的供体。根据吸收光谱研究,循环伏安法和DFT计算的结果,提出了这些还原反应的机理顺序,包括对Ar-DMBIH的芳基发色团进行初始光激发,然后单电子转移(SET)到有机物底物产生苯并咪唑啉的自由基阳离子和底物的自由基阴离子。
