Abstract
Chiral amines bearing a β-methyl group on the chiral center, and their derivatives, are key structural elements in natural products and pharmaceuticals.[1–3] For example, compound A is a key intermediate in the synthesis of the leukotrienes (LTs) receptor antagonist (Zeneca ZD3532, a phase II drug candidate; Scheme 1). This compound is particularly useful for the treatment of asthma.[2] Compound B (NPS 1392) is a potent stereoselective antagonist of ...
