Die Regioselektivitat dieser Art von Aminomethylierung zeigt sich z. B. auch bei den Re-aktionen von 2-Methyl-l-trimethylsilyloxy-cyclohexen und von 4a-Methyl-2-trimethyl-silyloxy-3,4,4a,5,6,7-hexahydro-naphthalin mit N,N-Dimethyl-methaniminium-jodid, welche unter ausschlieBlicher Bildung von 2-(Dimethylammo-methyl)-2-methyl-l-oxo-cy-clohexan (65%) bzw. 8-(Dimethylamino-methyl)-4u.-methyl-2-oxo-2,3,4,4a,5,6,7,8-octa-hydro-naphthalin (65%) verlaufen1. [Pg.1060]

Das ans Benzyl-dimethyl-(2-oxo-2-phenyl-ethyl)-ammonium-broniid durch Dehydrobro-mierung mittels Natronlauge erhaltliche N-Ylid kann, nach Isolierung in wasserfreier Form, thermisch in fast quantitativer Ausbeute zu 2-Dimethylamino-l,3-diphenyl-l-oxo-propan (X = H R = CgH,) umgelagert werden2. [Pg.1152]

Much work has been done on configuration and conformation, e.g. of 2-methoxy-2-oxo-4,5-diphenyl-l,3,2-dioxaphospholanes with 170 and lsO labelled reagents (81CC245). A large number of 2-dimethylamino-l,3,2-dioxaphospholanes or 3-methoxy-2-methyl-l,3,2,-oxazaphospholanes are mentioned in a recent publication, in which spiro compounds of the general structure (108) were prepared by addition to diethyl azodicarboxylate (equation (69)) (80PS(8)147>. [Pg.523]

A similar reaction of 5-oxo-4-phenyl-4,5-dihydro-l//-l,2.4-bcnzotriazepine-3-carbonyl chloride with 2-(dimethylamino)ethanol gave 2-(dimcthylamino)elhyl 5-oxo-4-phenyl-4,5-dihydro-l U-, 2,4-benzotri-azcpine-3-carboxylate (11c) yield 54% mp 130-132 C. [Pg.461]

Zur Aminomcthylierung von symmetrischen Dialkyl-ketonen (z. B. Cycloalkanonen) und von Ketonen mit nur einer substituierbarcn a-Stellung eignet sich ein einfaches Verfahren, bei welchem das Keton zunachst mit Kalium-hydrid in Tetrahydrofuran behandelt und danach mit N,N-Dimethyl-methaniminium-iodid umgesetzt wird. Man erhalt auf diese Weisez.B. 2- (Dimethylamino-methyl)-l-oxo-cyclohexan (88%) und 3-Dimethylamino-2-methyl-1-oxo-1 -phenyl-propan (75%)2. [Pg.1059]

Analog lassen sich aus Cyclopentanon oder aus Campher 2-(Dime.thylamino-methyl)-l-oxo-cyclopentan (60%) bzw. 3-[ Dimethylamino-methyl)-2-oxo-l,7,7-trimethyl-hicyclo [2.2.1] heptan (70%) herstcllen2. Im Fall unsymmetrischer Dialkyl-ketone wird bcvorzugt das thermodynamisch stabilere Produkt gebildet. [Pg.1059]
