The present invention provides pharmaceutical compositions comprising substituted 1,4 naphthoquinones that are effective in preventing oligomerization of beta amyloid and subsequent pathologies associated with amyloid fibrils. These compositions are useful for the treatment of disease involving amyloidogenesis including neurodegenerative diseases such as Alzheimer's Disease or senile dementia. Particularly effective compositions comprise 1,4 naphthoquinones substituted with an amino acid residue selected from a heterocyclic or aromatic amino acid.

amine-alkylation of quinones with amines and alkanes in the presence of di-tert-butyl peroxide (DTBP) was developed via a radical reaction process. Various alkanes and aromatic or aliphatic amines with diverse structures and electronic properties are suitable substrates, and the chirality of amines can be maintained for the transformation. This method has high step and atom economy for straightforward access
