Benzyl alcohol is converted into a variety of α-substituted derivatives by a one-pot sequence involving lithiation of an intermediate hemicarbonate ester. Benzylamine is similarly converted by a one-pot sequence to α-substituted benzylamines: here an intermediate carbamate salt is involved.
The present invention relates to chemokine receptor binding compounds, pharmaceutical compositions and their use. More specifically, the present invention relates to modulators of chemokine receptor activity, preferably modulators of CCR4 or CCR5. In one aspect, these compounds demonstrate protective effects against infection of target cells by a human immunodeficiency virus (HIV).
