We describe here the first total synthesis of the two natural 1,2,3,4-tetrahydronaphtho[2,1-f]isoquinolines, annoretine and litebamine, from [2-(2-styrylphenyl)ethyl]methylcarbamic acid ethyl esters. The key steps were the Bischler-Napieralski cyclization

Here we describe the first total synthesis of the 1,2,3,4-tetrahydronaphtho[2,1-f]isoquinoline (6) annoretine from N-carbethoxy-o-styrylphenylethylamines 2. The key steps were the Bischler-Napieralski reaction to form the isoquinoline unit and photocycliz
Syntheses og Stilbenes with a C2-Sidechain in o-Position and of their Deuteriated Analogues

, p. 511 - 532 (2007/10/02)
Syntheses of o-(β-aminoethyl)-stilbene-urethanes (types 1, 2 and 3) and o-(β-phenethyl)-stilbenes 4 are described.The urethanes are obtained by degradation of 1-benzyl-1,2,3,4-tetrahydroisoquinolines with ethylchloroformate; 4 is synthesized by reduction of desoxybenzoines, followed by o-formylation and Wittig-reaction.The deuteriated isotopomers were obtained via the corresponding deuteriated precursors. - Keywords: Stilbenes, o-substituted; Deuteriated compounds
Reductive Dicarbonyl Coupling with Low-valent Titanium Reagents: a New Entry to Phenanthrene Alkaloids
Seijas, Julio A.,Lera, Angel R. de,Villaverde, M. Carmen,Castedo, Luis
, p. 839 - 840 (2007/10/02)
A new and direct synthesis of phenanthrene alkaloids using a low-valent titanium reagent is described which is compatible with ethoxycarbonyl as the N-protecting group.
