    Synthesis and antifungal activity of oxygenated cholesterol derivatives
    摘要:
    A series of oxygenated cholesterol derivatives were prepared from new synthetic methods and evaluated for their in vitro antimicrobial properties against human pathogens. The activity was highly dependent on the structure of the different compounds involved. The best results were obtained with hydroxy ketones 2, 4 and 5 and diketone 7 exhibiting activities against S. cerevisiae (ATCC 28383) and Candida albicans (CIP 1663-86). For example, compound 2 exhibited high activities against C. albicans (CIP 1663-86) and Amphotericine B and miconazole resistant strain C. albicans (CIP 1180-79) at a concentration of 1.5 mu g/mL.

    Terminal acetals were selectively synthesized from various unbiased aliphatic terminal alkenes and 1,2-, 1,3-, or 1,4-diols using a PdCl2(MeCN)2/CuCl catalyst system in the presence of p-toluquinone under 1 atm of O2 and mild reaction conditions. The slow addition of terminal alkenes suppressed the isomerization to internal alkenes successfully. Electron-deficient cyclic alkenes, such as p-toluquinone
    在1 atm下在对甲苯醌存在下,使用PdCl 2(MeCN)2 / CuCl催化剂体系,由各种无偏的脂族末端烯烃和1,2-,1,3-或1,4-二醇选择性合成末端缩醛。O 2和温和的反应条件。末端烯烃的缓慢添加成功地抑制了异构化为内部烯烃。缺电子的环状烯烃,例如对甲苯醌,是增强催化活性和抗马尔科夫尼科夫选择性的关键添加剂。发现烯烃中的卤素基团起导向基团的作用,抑制了异构化并有效地提高了选择性。

    Direct conversion of aldehydes and ketones into alkylboronic esters via deoxygenative borylation represents an unknown yet highly desirable transformation. Herein, we present a one-step and metal-free method for carbonyl deoxy-borylation under mild conditions. A wide range of aromatic aldehydes and ketones are tolerated and successfully converted into the corresponding benzylboronates. By the same
