Herein we report a practical protocol for the visible-light-induced regiodivergent radical hydropyridylation of unactivated alkenes using pyridinium salts. This approach provides a unified synthetic platform to control the regioselectivity of the synthesis of linear or branched C4-alkylated pyridines. A remarkable selectivity switch from the anti-Markovnikov to the Markovnikov product can be achieved by the addition of tetrabutylammonium bromide. The versatility of this protocol is further demonstrated based on the late-stage functionalization in pharmaceuticals.

, (2008/06/13)
Novel 5-alkoxy tryptamine derivatives are provided, corresponding to the general formula: STR1 in which R may be alkaline, X may be amino, and Y is various N-heterocyclic or N-branched chain moieties. The compounds show selective binding to 5-HT 1D receptor subtypes, and have potential pharmaceutical utility in manufacture of migraine-treating drugs.

In the title reactions, N-(ω-bromoalkyl)phthalimides were ambident electrophiles.The carbanion of straight chain ester enolates (I, R1=H) attacked the carbonyl carbon atom of phthalimide moiety to give several types of compounds.
