Brønsted or Lewis acid assisted activation of an imidogold precatalyst (L-Au-Pht, Pht = phthalimide) offers a superior way to generate cationic gold compared with the commonly used silver-based system. It is also broadly applicable for most common gold-catalyzed reactions. For reactions that require milder conditions, milder acids can be used for optimized efficiency.

The ring opening of some phthalimide derivatives with sodium borohydride in methanol/water (6:1) afforded the corresponding 2-hydroxymethylbenzamides irrespective of the substituents. The most active members of the series evaluated for anti-inflammatory and analgesic activities were 2-hydroxymethyl-N-[4-(2-methoxyphenyl)-piperazin-1-yl]-ethylbenzamide (3d) and 2-hydroxymethyl-N-[4-(2-methoxyphe...

A series of annulated 7-membered oxazepine and 8-membered oxazocine derivatives were synthesized by photoreaction of phthalimide derivatives and an alkene. The antimicrobial activities of the synthesized compounds were evaluated, and compounds 18 and 20 exhibited best antibacterial activity against Gram-positive bacteria. The relationships between structure (especially steric structure) and ant...

nBu4NI-Catalyzed oxidative imidation of ketones and imides for the synthesis of α-amino ketones were realized for the first time. The methodology is characterized by its wide substrate scope even for acetone with readily available phthalimide, saccharin and succinimide, which opens a new pathway for direct imidation of ketones.

The nickel-mediated cross-coupling of phthalimides with diorganozinc reagents proceeds via a decarbonylative process to produce ortho-substituted benzamides in high yields. In addition to tolerating diverse phthalimide functionality, including alkyl, aryl, and heteroatom containing substituents, this methodology proceeds smoothly with diorganozinc reagents prepared from aryl bromides and utiliz...

2'-Deoxy-2'-N-phthaloyl nucleosides were prepared from arabino nucleosides by triflate displacement with phthalimide in the presence of DBU. The corresponding phosphoramidites suitable for automated oligonucleotide synthesis were also synthesized. The scalability of described procedures was demonstrated on a 100-g scale preparation of 2'-deoxy-2'-amino-C phosphoramidite.
