- Discovery and evaluation of 3,5-disubstituted indole derivatives as Pim kinase inhibitors
-
Pim kinases are promising therapeutic targets for the treatment of hematological cancers. A potent Pim kinase inhibitor 7f, derived from meridianin C, was further optimized by the replacement of 2-aminopyrimidine with substituted benzene. The optimization of the C-3 and C-5 positions of indole yielded compound 43 with improved cellular potency and high selectivity against a panel of 14 different kinases.

- The first regioselective metalation and functionalization of unprotected 4-halobenzoic acids
-
(Chemical Equation Presented) By treatment with s-BuLi, s-BuLi/TMEDA, or t-BuLi at ～-78°C, 4-fluoro- and 4-chlorobenzoic acids (1a,b) are metalated preferentially in the position adjacent to the carboxylate. A complete reversal in regioselectivity is observed for 1a when treated with LTMP; a sequential process involving a rapid intraaggregate lithiation through a quasi dianion complex "QUADAC" is postulated to explain the unusual reactivity of Me2S2 and I2.

- Enantiospecific synthesis of SB 214857, a potent, orally active, nonpeptide fibrinogen receptor antagonist
-
An enantiospecific synthesis of SB 214857, a potent, nonpeptide fibrinogen receptor antagonist, is reported. The synthetic route employs as a key step an intramolecular aryl fluoride displacement to form the seven-membered ring of the 1,4-benzodiazepine s

- Directed lithiation of unprotected benzoic acids
-
Benzoic acid gives the ortho-lithiated species 1 under standard conditions (s-BuLi-TMEDA-THF, -90 deg C).Reaction of 1 at -78 deg C with either methyl iodide, dimethyl disulfide, hexachloroethane, or 1,2-dibromotetrachloroethane gives the ortho-substituted product.Intramolecular competition between the carboxylic acid and methoxy, chloro, fluoro, or diethylamido functions in ortho- and -para-substituted benzoic acids establishes the carboxylic acid group to be of intermediate capacity in directing metallation.Complimentarity of directing effects is observed with the chloro and fluoro groups in the meta-substituted benzoic acid but not with the methoxy and trifluoromethyl groups.Electrophile introduction into meta- and para-lithiated benzoates occurs with equal efficacy and comparable scope.The 2,4-dihalogenobenzoic acids undergo hydrogen/metal exchange at the position flanked by both halogen substituents. 2,2-Difluoro-1,3-benzodioxole-4-carboxylic acid undergoes lithiation adjacent to the oxygen atom.By use of such methods, routes to benzoic acids contiguously tri- and tetra-substituted with a variety of functionalities have been developed.
