A novel ionic liquid methodology for pyrrole C-alkylation is described (Equation 136) <20050L1231>. The pyrrole alkylation is achieved with various simple alkyl halides (1-bromopentadecane, l-(bromomethyl)-, l-(3-chloropropyl)- and l-(3-iodopropyl)benzenes, 2-(2-bromoethyl)- and 2-(3-bromopropyl)naphthalenes) and mesylates (3-phenylpropyl-, l-methyl-3-phenylpropyl-, 2-(2-naphthyl)ethyl- and 3-(2-naphthyl)propyl methanesulfonates) selectively at C(2)- and C(5)-positions in good yields with minimal by-products under relatively mild conditions in various ionic liquids. 2-(3-Phenylpropyl)pyrrole 569 was synthesized from pyrrole and l-bromo-3-phenylpropane in a mixed solvent system, [Bmim][SbF6] and MeCN, in 81% yield at 115°C for 44h with 5% yield of dialkylated compound. 

A solution of the pinacol ester of diboronic acid (1 mmol), l-bromo-3,4-methylenedioxy benzene (2 mmol), 10% Pd/C (80mg) and CS2CO3 (3.7 mmol) were dissolved in 10ml methyl alcohol and heated to 55 °C 16 hours. GC analysis indicated that the product constituted of 83.5% 2-(bisl,3-benzodioxole and 16.5% l-bromo-3,4-methylenedioxy)benzene.

Typical procedure. l-Bromo-d-methyl-S-nitrothiophene-S-carbonitrile 1398 [1063] A solution of 2-bromo-4-methyl-5-nitrothiophene-3-carboxamide (2.2 g) in acetic anhydride (33 mL) was refluxed for 6 h. The reaction mixture was then concentrated under reduced pressure and the residue was chromatographed on a column of silica gel eluting with benzene. The nitrile obtained was crystallized from methanol mp 125-126 °C (no yield quoted). 

Condensation of l-bromo-2-methoxy-4-methyl benzene (64) with 5,6-dimethoxyaniline acetate (65) in pyridine in the presence of Cu and K2CO3 and subsequent hydrolysis with 20% KOH furnished the di-phenylamine derivative (66) which on treatment with palladium acetate in DMF afforded murrayastine (13). Condensation of l-bromo-3-methoxy-4-methylbenzene (67) with the dimethyl acetal of 6-formyl-5-methoxyaniline acetate (68) furnished the diphenylamine derivative (69) which on hydrolysis and on subsequent cyclisation furnished murray-aline (14). 

Bromo-3-iodo-l-(4-methylphenylsulfonyl)indole (0.476 g, 1.00 mmol), methyl acrylate (0.108 g, 1.25 mmol), EtjN (0.127 g, 1.25 mmol) and Pd(OAc)2 (11 mg, 0.050 mmol) were mixed in a tube, purged with argon and the tube was sealed and heated to 100°C for 1 h. After cooling, it was opened and mixed with CH2CI2 (50 ml). The solution was washed with water and dried (Na SOJ. The residue was purified by chromatography on silica using 1 3 benzene-hexane for elution. The yield was 0.350 g (81%). 

Benzene-l,4-diols are oxidized to quinones by benzyltrimethylammonium tribromide under mild conditions in almost quantitative yields [6]. With an excess of the tribromide further reaction produces the 2-bromo-l, 4-quinones. This oxidation is in contrast to the analogous reaction of phenols, which produces bromophenols (see Section 2.3). Hindered 4-methyl-phenols are oxidized to the corresponding benzyl alcohols, benzaldehydes, bromomethyl derivatives and 4-bromo-4-methylcyclo-hexa-2,5-dien-l-ones [7]. Benzylic alcohols are oxidized under neutral or basic conditions to yield the corresponding aldehydes (>70%) oxidation with an excess of the reagent produces the benzoic acids (>90%) [8],...
