AN IMPROVED SYNTHESIS OFN-BOC PROTECTED ARYL AMINES
摘要:
There are several known methods of protecting amines as their Boc derivatives. For less nucleophilic amines such as aryl amines these methods often give poor yields and are generally not satisfactory. Here, Boc aryl amines are obtained by first introducing two Boc groups followed by selective removal of one of them. This procedure works well for a number highly sterically hindered substrates as well as electron deficient and electron rich aryl amines.

The invention provides a novel class of compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with Toll-Like Receptors, including TLR7 and TLR8. In one aspect, the compounds are useful as adjuvants for enhancing the effectiveness of a vaccine (formula I) wherein: X3 is N; X4 is N Or CR3; X5 is -CR4=CR5.
A Pd-catalyzed enantioselective γ-selective arylation of β, γ-unsaturated butenolides is reported. The P-chiral phosphine ligand-AntPhos is essential for the observed high γ-selectivity, excellent enantioselectivity and good yields.
