developed for asymmetric Suzuki–Miyaura couplings of challenging heterocyclic substrates. Computer modeling pointed to a tunable, yet unexplored quadrant in BI‐DIME, leading to the discovery of the 3′,5′‐dimethyl‐substituted ligand which improved the atropisomeric selectivity of the Suzuki–Miyaura reaction from the previously reported 5:1 dr to 15:1 dr for the synthesis of a challengingHIVintegrase intermediate

The present invention is directed to an improved process for the preparation of Compounds of Formula (I) or salts thereof which are useful in the treatment of HIV infection. In particular, the present invention is directed to an improved process for the preparation of (2S)-2-tert-butoxy-2-(4-(2,3-dihydropyrano[4,3,2-de]quinolin-7-yl)- 2-methylquinolin-3-yl)acetic acid or salt thereof which is useful in the treatment of HIV infection. R4 is selected from the group consisting of (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), (n) and (o); and R6 and R7 are each independently selected from H, halo and (C1-6) alkyl.
