Directed ortho-Metalation–Cross-Coupling Strategies. One-Pot Suzuki Reaction to Biaryl and Heterobiaryl Sulfonamides
摘要:
A general synthesis of stable ortho-boropinacolato aryl and heteroaryl sulfonamides by directed ortho-metalation (DoM) and either MeOBPin or i-PrOBpin electrophile quench, 3 -> 4, is described. A one-pot metalation-Suzuki cross-coupling procedure for the synthesis of biaryis and heteroblaryls, 3 -> 5, and a complementary DoM-Ir-catalyzed boronation sequence (Scheme 6) are delineated.

A novel method toward synthesis of sulfonamides and β-arylsulfonyl enamines has been developed via I2/TBHP mediated C–N and C–H bond cleavage of tertiaryamines, which features highly selective formation of two different target products depending on the reaction solvent. The experimental results reveal that H2O as the solvent could effectively achieve the C–N bond cleavage to produce sulfonamides due

This invention offers an effective method of decreasing expression of apolipoprotein E and increasing expression of at least one of either LDL-receptor protein or AbcA1 protein including selecting mammalian cells expressing apoE and at least one of either LDL-receptor protein or AbcA1 protein, contacting the mammalian cell with an effective amount of a compound having general formula (I) or general formula (II) in an amount sufficient to decrease expression of the apoE and increase expression of at least one of the LDL-receptor protein or the AbcA1 protein in the mammalian cell.
