A novel method for the concise synthesis of cyclohepta[b]indoles in high yields was developed. The method involves a visible-light-induced, photocatalyzed [2+2]-cycloaddition/ retro-Mannich-type reaction of enaminones such as I to yield cycloheptaindoles such as II. Exptl. and computational studies suggested that the reaction is a photoredox process initiated by single-electron oxidation of enaminones, which undergo subsequent cyclobutane formation and rapid fragmentation of the intermediate radical cations to form cyclohepta[b]indoles.H-Trp-OMe.HCl(cas: 7524-52-9Name: H-Trp-OMe.HCl) was used in this study.
H-Trp-OMe.HCl(cas:7524-52-9) is one of amino acid derivatives. Amino acid derivatives represent an important category of skin penetration promoters. These compounds possess hydrophobic chains attached to an amino acid headgroup via a biodegradable ester bond. Due to the amphiphilic nature of these derivatives, it is possible for them to enter into the SC lipid barrier and significantly disorganize skin membrane lipids.Name: H-Trp-OMe.HCl
