A series of L-pyroglutamic acid analogues from natural product lead were designed and synthesized, as well as their antifungal activities against Phytophthora infestans, neuritogenic activities, antibacterial activities and anti-inflammatory activities are described. The bioassays and SAR study showed that the majority of L-pyroglutamic acid esters have a significant antifungal activity against P. infestans, especially 2d and 2j demonstrated the best activities with EC50 values of 1.44 and 1.21 μg mL?1, which were about seven times that of commercial azoxystrobin (7.85 μg mL?1). Moreover, compounds 2e, 2g and 4d displayed anti-inflammatory activity against LPS-induced NO production in BV-2 microglial cells; neuritogenic activity in NGF-induced PC-12 cells is the same activity. This study demonstrates that compounds 2d and 2j are potential drugs to control P. infestans.

Chiral diamides [(2S)-5-oxo-2-(arylamino)carbonylpyrrolidines] derived from the abundantly available (S)-glutamic/(S)-pyroglutamic acids were successfully utilized as effective chiral catalytic precursors in the borane-mediated asymmetric reduction of prochiral ketones in refluxing toluene, to provide the corresponding secondary alcohols with up to 91% enantiomeric purities.
