    Metal-ammonia reduction and reductive alkylation of N-alkylnaphthalenesulfonamides. A new route to substituted naphthalenes
    摘要:
    Conditions have been found for 1,4-reduction of aromatic sulfonamides (conveniently monitored by electrical conductivity), using metals in THF/liquid ammonia on the pre-formed N-lithium salts (BuLi), without concomitant C-S reductive cleavage. The resulting 1,4-dihydro compounds could be alkylated, either in situ (in the case of simple unfunctionalized halides only) or, following isolation, after further N-alkylation and then forming the monoanion, or after forming the dianion of the N-monoalkylated dihydrosulfonamide, generally using as base n-butyllithium (a simple titration procedure). In the former case functionalized electrophiles (bromo esters, chloroformates) could be utilized. The ratio of alpha- to gamma-alkylation was dependent on the method of alkylation, the reaction medium, the nature of the N-alkyl group(s), and whether a monoanion or a dianion served as substrate. Gamma-Alkylation products could in some cases be further alpha-substituted. The alpha-substituted products aromatized, with loss of SO2 and amine, by heating, whereas gamma-substitution products required hydrolysis by aqueous alkali; this greatly facilitated separation where mixtures were formed. Thus, this dihydrosulfonamide route constitutes a novel and nucleophilic route to 1-substituted, 2-substituted, and, notably, 1,3-disubstituted naphthalenes.

    The present invention provides a process for the preparation of some novel 2-aryl and 2,2-diaryl aldehydes and analogues which are privileged intermediates for commercially important nonsteroidal anti-inflammatory drugs including naproxen, flurbiprofen and potent anticancer drug candidates, including phenstatin through a unique single step synthetic methodology utilizing easily available substrates in the form of aryl alkenes as well as environmentally benign aqueous reaction conditions in the form of solvents such as mixtures of water and DMSO or Dioxane and reagents N-bromosuccinimide, N-iodosuccinimide, N-cholorosuccinimide and phase transfer catalyst such as cetyltrimethyl ammonium bromide, N-hexyl ammonium chloride for a reaction time varying from 1 min-30 min, depending upon microwave or conventional heating, without using expensive transition metal catalysts or lewis acids/bases with yield varying from 35-55%, depending upon the solvent and substrate used. The developed method provides a clean and convenient alternative to access a diverse range of medicinally important 2-aryl and 2,2-diaryl aldehyde based scaffolds in lieu of the conventional multistep protocols employing expensive and hazardous transition metal catalysts and lewis acids/bases.
