Fast, simple and high-yield synthesis continues to be a major challenge for synthetic organic chemists. Among nitrogen-containing heterocyclic compounds, 1 the benzimidazole ring is an important pharmacophore for modern drug discovery. 2 Benzimidazoles have significant biological properties including anticancer, 3 anti-HIV, 4 antibacterial, 5 anti-ulcer, 6 anti-tumor 7 and enzyme inhibitory 8 properties. Benzimidazoles are also important intermediates in organic reactions. 9 Due to the importance of benzimidazoles, interest in the synthesis of these compounds has increased. The most common method is the condensation of o -aryldiamines and carbonyl compounds, especially aldehydes; and the wide availability of the latter makes this route particularly attractive for the production of 2-arylsubstituted benzimidazoles. 10 Numerous oxidative and catalytic reagents have been employed in this method, including Oxone, 11 In(OTf) 312 , FeCl 3 (cid:1) 6H 2 O, 13 I 2 /KI/K 2 CO 314 , sulfamic acid, 15 KHSO 416 , TBAF, 17 SBSA, 18 TiCl 3 OTf 19 and VOSO 4 . 20 These catalysts have been useful for their own purposes in facilitating the synthesis of the expected compounds.

The use of green catalysts is one of the most crucial elements in the greening of synthetic chemical processes. In line with this, current research initiatives in our lab have concentrated on the creation of green catalysts 1 – 4 for organic synthesis. Surfactant molecules can group together in an aqueous phase under ambient conditions to create micelles, which have a hydrophobic core and a hydrophilic corona. The widespread and in-depth study of micellar surfactants as catalysts for various reactions in aqueous solutions opens the door for more synthesis methods using aqueous media. Sodium stearate is a common surfactant found in frequently-used preparations. However, there are not many studies on organic reactions using sodium stearate as a catalyst. 5 In this context, we present below a straightforward and effective technique for the synthesis of tetrahy-drobenzo[ b ]pyrans using a Lewis base-surfactant-combined (LBSC) catalyzed three-component one-pot reaction in an aqueous micellar medium. Pyrans have such noteworthy pharmacological characteristics (Figure 1) as Chk1 kinase inhibitory, 6 analgesic, 7 anticancer, 8 vasodilatory, 9 antihypertensive, hepatoprotective, cardiotonic, 10 vasodilator, 11 anti-leukemic, 12,13 emetic, 14 anti-anaphylactic, 15 diuretic 16 and anti-Alzheimer 17 properties.

In continuation of our interest to functionalize selectively the indole-2,3 positions, we now describe the synthesis of 2-bromo-1-(phenylsulfonyl)-1H-indol-3-yl trifluoromethanesulfonate (1) as a potentially useful precursor for the selective functionalization of the indole positions. Our synthesis of 1 is shown in Scheme 1. Following the conversion of commercially available 2-aminoacetophenone (2) to sulfonamide 3, the four subsequent reactions to give 1 were performed with only one intermediate purification due to the presumed formation of indigo by-products (blue-purple discoloration), and the possible lachymatory effects of bromide 4. Bromination of 3 to 4 was subject to capricious reaction times, but we found that the addition of catalytic amounts of concentrated HBr eliminated this phenomenon, presumably by supplying sufficient HBr to the mixture to initiate formation of Br2. Over-bromination of 3 was minimized by exclusion of air. The mixture of 4, containing some ketone and dibromoketone, was converted to indolin-3-one 5 in 60% yield after purification. Subsequent bromination to 6 and triflate formation to 1 proceeded in 54% yield for the two steps. Attempts to brominate (NBS, Br2) the known 1-(phenylsulfonyl)-1H-indol-3-yl trifluoromethanesulfonate to afford 1 were not successful. In summary, we disclose a straightforward synthesis of compound 1 from 2-aminoacetophenone. This new 2,3-unsymmetrically-disubstituted indole should find utility in the synthesis of a wide range of indoles in contrast to, for example, 2,3-dihaloindoles for which regioselective reactions have proven difficult.
