有三尖的

A novel endocyclic enamine cyclopentenone annulation was discovered and rationalized as an unusual Nazarov-type electrocyclization, which would have broad applications in the synthesis of natural alkaloids and other heterocycles.

我们在合成路线一、路线二中用的6-6元环系到7-5元环系的还原重排反应，在温和的酸性还原条件下即能发生，这说明在三尖杉碱的生物合成中6-6元环到7-5元环的还原重排步骤是非常有可能发生的；因此，我们的合成路线二中可认为是生物合成过程。

Results Fifty-eight (93.5%) cases SVA were preoperatively discovered by echocardiography, while 2 (3.2%) misdiagnosed as tetralogy of Fallot and tricuspid regurgitation and 2 (3.2%) missed diagnosis.Accompanying teratisms included frequently ventricular septal defect (33 cases, 53.2 %) and aortic valve dysplasia(11 cases, 17.7%).The rupture site and the drainage chamber were essentially consisted with surgery,while the size of VSD measured by echocardiography was significantly smaller than that measured in operation.

结果 62例患者中，术前超声诊断Valsalva窦瘤破裂58例(符合率93.5%)，误诊为法洛四联症、三尖瓣反流各1例(3.2%)，漏诊2例(3.2%)；常见的合并畸形有干下室间隔缺损(33例，53.2%)、主动脉瓣发育不良伴重度主动脉瓣关闭不全(11例，17.7%)；超声报告窦瘤部位及破人腔室与手术结果一致，超声所测室间隔缺损大小明显低于手术所见。
