Unprecedented directing effect of bromine on the regioselectivity of addition of stannylated oxazolines to substituted 2-bromo-1,4-naphthoquinones. Synthesis of 4-oxazolinyl-1,2-naphthoquinones

Research has been conducted on the stannylated oxazolines. The addition of these oxazolines to the bromonaphthoquinones at the carbonyl group vicinal to the bromine atom has been investigated and the results are presented.
