The multicomponent approach to N-methyl peptides: total synthesis of antibacterial (–)-viridic acid and analogues

Beilstein Journal of Organic Chemistry, 2012
Two syntheses of natural viridic acid, an unusual triply N-methylated peptide with two anthranilate units, are presented. The first one is based on peptide-coupling strategies and affords the optically active natural product in 20% overall yield over six

Silver(I) triflate-catalyzed post-Ugi synthesis of pyrazolodiazepines

Beilstein Journal of Organic Chemistry
A silver(I) triflate-catalyzed post-Ugi assembly of novel pyrazolo[1,5-a][1,4]diazepine scaffolds is reported offering high yields (up to 98%) under mild conditions.
