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 previouslyimplantedpacemakers, we tested a newstressechocardiographymethodusing incremental ventricularpacing by already implantedpacemakers. METHODS We studied prospectively 25 consecutive patients who underwent stressechocardiography with increasing ventricularpacing up to either 85% of the age-predicted maximal

Acyclic stereocontrol based on nonchelation-controlled ene reactions with α-haloaldehydes
作者:Koichi Mikami、Teck-Peng Loh、Takeshi Nakai
DOI:10.1039/c39910000077
日期:——
Aluminium(III)-promoted ene reactions with α-haloaldehydes are shown to exhibit a high anti-diastereofacial (non-chelation) selection or syn-diastereoselection to afford an efficient method for preparing stereochemically-defined β-haloalcohols including the 22R-hydroxy side chain unit in steroids.

This application relates to compounds of Formula (I):
or pharmaceutically acceptable salts or stereoisomers thereof, which modulate the activity of adenosine receptors, such as subtypes A2A and A2B receptors, and are useful in the treatment of diseases related to the activity of adenosine receptors including, for example, cancer, inflammatory diseases, cardiovascular diseases, and neurodegenerative diseases.
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.
