One-pot synthesis of benzo[f]quinolin-3-ones and benzo[a]phenanthridein-5- ones by the photoanuulation of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1- ones to phenylacetylene

The one-pot synthesis of benzo[f]quinolin-3-ones and benzo[a] phenanthridein-5-ones was achieved by the inter- and intramolecular photoannulation of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1-ones with phenylacetylene or tethered phenylacetylene. The reactions were proceeded by photoaddition of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1-ones to phenylacetylene to give the chlorine-substituted stilbenoids, and then 6π electrocyclization of the stilbenoids and oxidation aromatization to afford the polycyclic products.

Nitrite anion: The key intermediate in alkyl nitrates degradative mechanism

Alkyl nitrates are metabolized in vitro to yield nitric oxide, and thiol groups have long been considered necessary cofactors. Here, we report evidence that no reaction between thiols and alkyl nitrates takes place in vitro, but stronger reducing agents, such as iron(II) derivatives, are necessary; alkoxy radicals and nitrite anions are the reaction intermediates. The latter, in slightly acidic conditions, can nitrosate thiols to the corresponding S-nitrosothiols, the real NO releasers.

FORMATION AND REARRANGEMENT OF THE GRIGNARD REAGENT FROM 2-PHENYLCYCLOBUTYLMETHYL BROMIDE

Reaction of cis- or trans-2-phenylcyclobutylmethyl bromide with magnesium produces the rearranged 5-phenyl-1-penten-5-ylmagnesium compound 7 in addition to the unrearranged Grignard reagent 6.The former appears to result from very rapid rearrangement of a radical intermediate in the process of Grignard reagent formation.Rearrangement of 6 to 7 also occurs, at a rate which is accelerated by the phenyl group.
