The previously reported ring-expansion strategy involving hydrolytically prone imidazoline rings was thought to include the formation of a hydrated imidazoline intermediate. In this work, we accessed the latter via the addition of a 2-aminoethyl side chain onto a lactam moiety. This led to an efficient three-atom ring expansion of diarene-fused [1.4]oxazepines and [1.4]thiazepines and led us to propose to term this common approach the hydrated imidazoline ring expansion (HIRE) reaction. The strategy was extended to the insertion of longer (containing up to five atoms) side chains, and thus, larger (11- to 12-membered) diarene-fused rings were obtained via the homo-HIRE and homo2-HIRE reactions, resp. This underscores the utility of the HIRE reaction for the preparation of medium-sized rings, an important class of chem. tools for interrogation of various biol. targets. The experimental process involved the reaction of tert-Butyl (5-aminopentyl)carbamate(cas: 51644-96-3Related Products of 51644-96-3)
Some of the reported applications of tert-Butyl (5-aminopentyl)carbamate(cas: 51644-96-3) include: synthesis of of a supermacrocycle that self-assemble to form organic nanotubes., preparation of water-soluble unsymmetrical sulforhodamine fluorophores from monobrominated sulfoxanthene dye, synthesis of functionalized porphyrins as biocompatible carrier system for photodynamic therapy (PDT).Related Products of 51644-96-3
