Integrin inhibitors based on the tripeptide sequence Arg-Gly-Asp (RGD) are potential therapeutics for the treatment of idiopathic pulmonary fibrosis (IPF). Herein, we describe an expeditious three-step synthetic sequence of Horner-Wadsworth-Emmons olefination, diimide reduction, and global deprotection to synthesise cores for these compounds in high yields (63-83% over 3 steps) with no need for chromatography. Key to this transformation is the phosphoramidate protecting group, which is stable to metalation steps.

The bisphosphine ligand 1c is highly efficient and selective for the asymmetric hydroformylation (AHF) of dihydrofuran and pyrrolines. The AHF of 2,3-dihydrofuran yielded the 2-carbaldehyde in up to 93% ee. The remarkable highest regioselectivity of 2,5-dihydrofuran was obtained to date up to 499 β-isomer/α-isomer with ligand 1c. Furthermore, the highest 96% and 92% ee values were accomplished using the same catalytic system in the AHF of N-Boc pyrroline 11 and 14.
