Phenols lateral lithiation

Better for the lateral lithiation of phenols are the A(,A(-dialkylcarbamate derivatives 533. These may be lithiated with LDA, allowing complete selectivity for the lateral position, presumably because this is the thermodynamic product . With i-BuLi, ortholithiation is... [Pg.609]

The best phenol-derived lateral director of all appears to be the diaminophosphoryl group. Lithiation of 536 at — 105°C with i-BuLi gives a highly reactive organolithium which adds to electrophiles even at —90°C (Scheme 212) . ... [Pg.610]
