    Determination of the absolute configuration of two α v β 6 integrin inhibitors for the treatment of idiopathic pulmonary fibrosis and investigations on the asymmetric 1,4-addition of arylboronic acids to crotonate esters bearing a C4-oxygen substituent
    摘要:
    The absolute configuration of two novel alpha(v)beta(6) integrin inhibitors was established via degradation to the corresponding C3-aryl substituted butyrolactone. The configuration of the resulting lactones was established by asymmetric synthesis using 1,4-addition of arylboronic acids to butenolide, catalysed by bis (norbornadiene)rhodium (I) tetrafluoroborate in the presence of (R)-BINAP, and confirmed by X-ray crystallography. Studies on arylboronic acid conjugate additions to acyclic crotonate esters bearing a gamma-oxygen substituent are also reported. Three Rh catalysts were investigated and the one giving the highest enantioselectivity was bis(norbornadiene)rhodium (I) tetrafluoroborate. (C) 2017 Elsevier Ltd. All rights reserved.

A variety of aryl substituents including morpholine, pyrazole, triazole, imidazole, and cyclic ether were screened in cell adhesion assays for affinity against αvβ1, αvβ3, αvβ5, αvβ6, and αvβ8 integrins. Numerous analogs with high affinity and selectivity for the αvβ6 integrin were identified. The analog (S)-3-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)-4-((R)-3-(2-(5,6,7,8-tetrahydro-1
