The development of the human lateral vestibular nucleus was studied on serial sections of the brain of 8 fetuses and neonates at 12-40 weeks of gestation, an infant at 2 months of age and an adult of 63 years using a microscope with a drawing tube and an image-analysing computer system. A morphometric analysis revealed that the lateral vestibular nucleus,(More)
[reaction: see text] One-pot allene synthesis from aryl iodides 1 and propargyldicyclohexylamine 2 proceeded in the presence of Pd(2)(dba)(3).CHCl(3) catalyst (2.5 mol %), 1,2-bis(diphenylphosphino)carborane 5 (10 mol %), CuI (15 mol %), and Et(3)N (150 mol %) to give the corresponding allenes 4 in good to high yields. Electron-deficient bidentate(More)
A series of allenic quinazolines were synthesized as receptor tyrosine kinase inhibitors by using a simple protocol for palladium-catalyzed allene transformation. Among the compounds synthesized, two allenic 4-anilinoquinazolines selectively suppressed epidermal growth factor receptor (EGFR) tyrosine kinase activity in vitro. According to immunoblot(More)
[reaction: see text] Propargylic diisopropylamines containing heterocycles, which were prepared readily from heterocyclic bromides and propargyldiisopropylamine by the Sonogashira coupling reaction, underwent the allene transformation reaction in the presence of Pd(2)(dba)(3).CHCl(3) catalyst (2.5 mol %) and 1,2-bis[bis(pentafluorophenyl)phosphino]ethane(More)
