Synthesis of 2-phosphonoheterocycles via base-promoted 5-endo cyclization

نویسندگان

چکیده

Herein, a synthesis of 2-phosphonodihydrofurans and 2-phosphonodihydropyrroles via 5-endo cyclization O-and N-propargylated compounds is described. The reaction promoted by potassium tert-butoxide allows fast access to interesting heterocycles which were easily converted into 2-arylated pyrroles under acidic conditions.

Copper-catalyzed 5-endo-trig cyclization of ketoxime carboxylates: a facile synthesis of 2-arylpyrroles.

A novel and facile copper-catalyzed 5-endo-trig cyclization of ketoxime carboxylates for the synthesis of 2-arylpyrroles has been developed. The reaction tolerates a range of functional groups and is a practical procedure for rapid synthesis of 2-arylpyrroles in high yields under mild conditions.

Catalytic enantioselective synthesis of indanes by a cation-directed 5-endo-trig cyclization.

5-Endo-trig cyclizations are generally considered to be kinetically unfavourable, as described by Baldwin's rules. Consequently, observation of this mode of reaction under kinetic control is rare. This is usually ascribed to challenges in achieving appropriate approach trajectories for orbital overlap in the transition state. Here, we describe a highly enantio- and diastereoselective route to c...

Facile synthesis of azaspirocycles via iron trichloride-promoted cyclization/chlorination of cyclic 8-aryl-5-aza-5-tosyl-2-en-7-yn-1-ols.

A simple and efficient FeCl(3)-promoted cyclization/chlorination of cyclic tosylamine-tethered 8-aryl-2-en-7-yn-1-ols was observed. The reaction proceeded instantaneously at 23 °C in air to afford (Z)-4-(arylchloromethylene)-substituted azaspirocycles in good to excellent yields. This transformation can also be applied to the synthesis of spirocarbocyclic analogues from cyclic 8-aryl-2-en-7-yn-...

First total synthesis of ent-gelsedine via a novel iodide-promoted allene N-acyliminium ion cyclization.

The first total synthesis of the oxindole alkaloid gelsedine (1) starting from (S)-malic acid is described. The key step is a novel iodide-promoted intramolecular reaction of an allene with an N-acyliminium ion intermediate which provided in a single step the bicyclic vinyl iodide 11. Other important steps are the highly stereoselective Pd-catalyzed Heck cyclization of N-methylanilide 23a which...
