, p. 213 - 216 (1999)
The enantiomerically enriched BOC-protected (4- pinacolylborono)phenylalanine methyl ester (8) is produced via enzymatic resolution of the racemic material, or direct synthesis from the corresponding iodide (or triflate), and undergoes Suzuki-Miyaura coup
Rhodium-Catalyzed Dealkenylative Arylation of Alkenes with Arylboronic Compounds

The C?C bond formation reaction represents a fundamental and important transformation in synthetic chemistry, and exploring new types of C?C bond formation reactions is recognized as appealing, yet challenging. Herein, we disclose the first example of rhodium-catalyzed dealkenylative arylation of alkenes with arylboronic compounds, thereby providing an unconventional access to bi(hetero)aryls with excellent chemoselectivity. In this method, C(aryl)?C(alkenyl) and C(alkenyl)?C(alkenyl) bonds in various alkenes and 1,3-dienes can be cleaved via a hydrometalation and followed by β-carbon elimination pathway for Suzuki–Miyaura reactions. Furthermore, a series of novel organic fluorescent molecules with excellent photophysical properties has been efficiently constructed with this protocol.

Two process routes for LX1031, a tryptophan hydroxylase inhibitor for the treatment of irritable bowel syndrome, were developed. They shared the same left-hand and right-hand starting materials as well as the penultimate intermediate. The chiral center in
