    Studies in Selectivity Aspects in the Synthesis of Aliphatic α-Bromoaldehydes
    摘要:
    A highly selective process scheme was developed to synthesize alpha-bromoaldehydes by regulating the important process parameters from a reaction-engineering point of view. Thus, alpha-bromobutyraldehyde and alpha-bromoheptaldehyde were synthesized in very high selectivity starting with butyraldehyde and heptaldehyde, In the bromination reaction at 40% conversion ratio, the selectivity was as high as 98% by using liquid bromine as the brominating agent.

  • Detection of coronary stenoses by stress echocardiography using a previously implanted pacemaker for ventricular pacing: Preliminary report of a new method

    infarction. HYPOTHESIS To detect significant coronary stenosis in patients with previously implanted pacemakers, we tested a new stress echocardiography method using incremental ventricular pacing by already implanted pacemakers. METHODS We studied prospectively 25 consecutive patients who underwent stress echocardiography with increasing ventricular pacing up to either 85% of the age-predicted maximal
    背景技术具有起搏器的患者的数量一直在增加,并且其中许多患者将出现胸痛或暗示心绞痛的症状。使用起搏器的患者很难通过无创方法检测和评估心肌缺血和冠状动脉疾病。通常,就缺血甚至急性心肌梗塞而言,静止和运动期间的心电图(ECG)都很难分析。假设为了检测先前植入起搏器的患者的严重冠状动脉狭窄,我们测试了一种新的应力超声心动图方法,该方法采用已经植入的起搏器进行增量心室起搏。方法我们前瞻性地研究了连续25例接受压力超声心动图检查的患者,这些患者的心室起搏增加至年龄预测的最大心率或胸痛的85%。阳性试验是由新的运动功能减退或至少在两个相邻地区壁运动的先前变化加重定义的。所有患者均进行了冠状动脉造影,以确定冠状动脉狭窄的存在和严重程度。结果在25项测试中,有11项(44%)因胸痛而停止使用。中度不适感为1(4%),血压下降为1(4%),其余12位患者(48%)的测试中达到了目标起搏率。没有并发症。13名患

    日期:2001.4
    The synthesis of two α-aminocyclopropanone hydrates is reported. These synthons could find biological applications by acting as transition-state analog inhibitors of hydrolytic enzymes, such as serine proteases.

  • The Mukaiyama reaction of ketene bis(trimethylsilyl) acetals with α-halo acetals
    作者:F.W.J. Demnitz
    DOI:10.1016/s0040-4039(01)93317-9
    日期:——
    Ketene bis(trimethylsilyl) acetals were reacted with α-halo acetals giving β-alkoxy-γ-halo acids which were converted to butenolides by reaction with two equivalents of base. This constitutes a novel and short butenolide synthesis.

    Nicolaou et al. reported the preparation of a polymer-bound selenium bromide and its applications in organic ~ynthesis.~ We previously described the formation of polymer-supported vinylic selenides, as well as the synthesis of carbonyl compounds on solid-phase! Herein, we report a very simple preparation of polystyrene-supported (4-phenylse1eno)morpholine and its application as a powerful reagent for
    近年来,随着组合化学的出现,聚合物支持的试剂在有机合成中重新流行起来。重要的优点之一是易于在反应结束时从产物混合物中分离和回收聚合物树脂。有机硒试剂引起了相当大的兴趣,特别是,原位形成的 4(arylse1eno)吗啉可用于在饱和醛的位置插入芳基硒基。 2a a-硒醛在有机合成中很重要;例如, a-硒醛可以通过卤化转化为a-卤代醛!然而,有机硒试剂总是有臭味,而且毒性很大。最近,Nicolaou 等人。报道了聚合物结合的溴化硒的制备及其在有机合成中的应用。~我们之前描述了聚合物负载的乙烯基硒化物的形成,以及羰基化合物在固相上的合成!在此,我们报告了一种非常简单的聚苯乙烯负载的 (4-苯基硒烯) 吗啉的制备及其作为饱和醛的 α-硒基化和通过固相卤化进行脱硒基化反应的强效试剂的应用(方案 I)。与非聚合物结合的试剂相比,这些新型聚合物负载硒试剂的一个显着优点是操作方便且完全无味。此外,使用简单
