We have recently discovered a tandem N-alkylation-C-allylation reaction of α-imino esters with organoaluminum reagents and allyltributyltin[1]. In this reaction, iminium salts were readily prepared in situ by the oxidation of aluminum enolates, and the subsequent nucleophilic addition proceeded smoothly to afford N-alkylation-C-allylation products in good yields. During these studies, we focused on the generation of iminium species 2 by oxidizing a readily accessible and stable enol derivative with oxidants. A convenient method has been found for the generation of α-alkoxycarbonyl iminium salts 2 from ketene silyl acetals and the subsequent reaction with nucleophiles[2].

1 Results We have already published a double nucleophilic addition reaction of α,β-unsaturated imines with several nucleophiles such as ketene silyl acetals, trimethylsilyl cyanides, trimethylsilyl azides and thiols[1]. However, it was not easy to use N-allylideneamine 2 derived from acrolein for such reactions. Since there is no substituent at the β-position, imine 2 has high reactivity and are prone to be polymerization. We report the first synthesis of N-allylideneamines 2 using the isomerization of ...

Coronary artery dissection due to blunt chest trauma (traumatic coronary artery dissection [TCAD]) may heal spontaneously, and some surgeons believe that conservative or elective treat-ments are sufficient, provided that there are no progressing ischemic symptoms. However, we report a patient who experienced sudden ventricular fibrillation (VF) during initial medical care for trauma injuries. The 32-year-old woman was riding in a passenger car when an accident occurred, and was subsequently transported to our emergency department. Twelve-lead electrocardiography revealed ST segment elevation in leads II, III, and aVF, although her vital signs remained stable. Therefore, we prioritized assessing the trauma at other sites, and VF suddenly occurred. Coronary angiography was performed with repeated defibrillation and chest compressions, which resulted in recovery of spontaneous circulation. Occlusion was observed in the right coronary artery, which we treated with balloon angioplasty. However, intravascular ultrasonography (IVUS) subsequently revealed coronary artery dissection, a stent was placed, and the patient successfully recovered. Therefore, IVUS may be useful for diagnosing TCAD, and swift intervention is needed if TCAD is detected.

Preparation of large mesoporous tin dioxide (lm-SnO_2) under various conditions was attempted by utilizing a self-assembly of a triblock copolymer,P123:(EO)_(20)(PO)_(70)(EO)_(20) or F127:(EO)_(106)(PO)_(70)(EO)_(106)(EO:ethylene oxide and PO: propylene oxide).The sensor fabricated from calcined lm-SnO_2 powder,which had been prepared by using P123 as a template,Na_2SnO_3 as a tin source,and TEOS as an additive ([TEOS]/[Na_2SnO_3]=0.5 in the precursor solution),showed the largest response to 1×10^(-3) hydrogen at 350℃among the sensors *** existence of two kinds of SnO_2 particles with different sizes (ca.100 nm and several nm in diameter) may be important to improve the hydrogen sensing properties drastically.

This paper presents finite element (FE) formulation of the viscoelastic materials described by fractional constitutive law. The time-domain three-dimensional constitutive equation is constructed. The FE equations are set up by treating the fractional operator as a special case of the hereditary integration. The equations are solved by numerical integration method. The numerical algorithm developed by the authors for Liouville-Riemann's fractional derivative was adopted to formulate FE procedures and extended to solve the more general case of the hereditary integration. The numerical examples were given to show the correctness and effectiveness of the integration algorithm.
