BACKGROUND: Herpetic necrotizing retinitis is a well-recognized entity. A few cases of herpetic non-necrotizing retinitis were previously reported.FINDINGS: We retrospectively report two cases of herpetic non-necrotizing retinopathy with a long follow-up. A 19-year-old woman presented with a bilateral diffuse...

A Radical Cyclization Approach to Isoindolobenzazepines. Synthesis of Lennoxamine.

The Journal of organic chemistry

J Org Chem. 1996 Apr 19;61(8):2780-2782. doi: 10.1021/jo952113k.

The alkaloid lennoxamine (1) was synthesized by transannular cyclization of a 10-membered lactam obtained by intramolecular addition of an aryl radical to a (trimethylsilyl)acetylene. The isoindolo[1,2-b][3]benzazepine skeleton present in lennoxamine was also obtained by means of regioselective 7-endo-trig radical...

We present a case of serous cystic pneumatosis of the small intestine, infrequently clinical entity. The case is commented and it revises the literature.

Stereoselective synthesis of highly functionalized 1,5-oxa-bridged cyclooctenes via a 3-oxidopyrylium-cyclopropenone acetal cycloaddition [corrected].

[reaction: see text] A [5C+2C] oxidopyrylium-cyclopropenone acetal cycloaddition followed by ring opening of the cyclopropane unit of the resulting adduct leads to highly substituted 1,5-oxa-bridged cyclooctenes containing up to four stereocenters. The protocol formally constitutes a [5C+3C] annulation process.

[reaction: see text] Readily available 4-propargyl-1,3-cyclohexanediones and cyclopentanediones can be chemo- and regioselectively cycloisomerized to synthetically appealing fused oxabicyclic systems by simply stirring at room temperature with catalytic amounts of an appropriate metal complex.

A new Ru-catalyzed cascade reaction forming polycyclic cyclohexadienes from 1,6-diynes and alkenes.

Functionalized bicyclic 1,3-cyclohexadienes can be easily prepared by a new cascade reaction which involves the Ru-catalyzed addition of acyclic alkenes to 1,6-diynes to give (Z)-hexatrienes, followed by a pure thermal 6e-pi electrocyclization.

Palladium-catalyzed [3 + 2] intramolecular cycloaddition of alk-5-enylidenecyclopropanes.

J Am Chem Soc. 2006 Jan 18;128(2):384-5. doi: 10.1021/ja054487t.

Readily accessible alk-5-enylidenecyclopropanes undergo [3 + 2] intramolecular cycloaddition reactions upon treatment with appropriate palladium complexes. The method allows the rapid and efficient assembly of a variety of bicyclo[3.3.0]octane systems with up to three stereocenters. Preliminary theoretical calculations uncovered...

Chem Commun (Camb). 2010 Jan 14;46(2):270-2. doi: 10.1039/b919258a. Epub 2009 Nov 27.

We report a Pd-catalyzed intramolecular [3C + 2C + 2C] cycloaddition between alkylidenecyclopropanes, alkynes and alkenes. The method provides synthetically relevant 5-7-5 tricyclic structures, with good chemoselectivity and complete diastereoselectivity.
