MeNH2 added to CH2:CMeCO2Me in MeOH to give MeNHCH2CHMeCO2Me, which was hydrolyzed to the acid; PrCO2H was converted to MeNHCH2CHEtCO2Me by successive bromination, esterification with MeOH, modified Reformatskii reaction to give HOCH2CHEtCO2Me, bromination, and amination with MeNH2. CH2:CRCO2H (R = Me, Et) were successively hydrobrominated, brominated, amidated with Et2NH, and aminated with MeNH2 to give MeNHCH2CHRCONEt2. MeNHCH2CHRCOR1 (R = Me, Et; R1 = OH, OMe, NEt2) reacted with 3-(2-bromoethyl)indole (from the esterification, LiAlH4 reduction, and bromination of indole-3-acetic acid) to give 5 LSD analogs I.

Ploypradith, Poonsakdi published the artcileUtility of Polymer-Supported Reagents in the Total Synthesis of Lamellarins, Related Products of bromides-buliding-blocks, the publication is Journal of Organic Chemistry (2005), 70(13), 5119-5125, database is CAplus and MEDLINE.

Four solid-supported reagents have been utilized in the multistep synthesis of lamellarins. The use of Amberlyst A-26 Br₃^– and polymer bound pyridine hydrobromide perbromide (PVPHP) for keto α-bromination of the less studied ortho-substituted acetophenone derivatives selectively furnished the corresponding monobromination products (phenacyl bromide derivatives), which were used directly in condensation reactions with benzyldihydroisoquinoline mediated by Amberlyst A-26 NaCO₃^–. The 2H-pyrrole carbonates subsequently underwent intramol. Friedel-Crafts transacylation followed by lactonization to provide the lamellarin skeleton (e.g. I). Alternatively, Amberlyst A-26 NaCO₃^– effectively served as base in condensation reaction of benzyldihydroisoquinoline with α-nitrocinnamate derivatives to provide the corresponding 2-ethoxycarbonyl pyrroles, which smoothly underwent O-debenzylation reaction followed by lactonization to furnish the lamellarin skeleton. The novel Amberlyst-15 mediated lactonization reactions effectively combined the otherwise two sep. steps into a single transformation.

Nganga, Joseph B. published the artcileDibromorhodamine-based photoredox catalysis under visible light for the colorimetric detection of Hg(II) ion, COA of Formula: C20H18BrN3, the publication is Bulletin of the Korean Chemical Society (2022), 43(7), 946-950, database is CAplus.

We demonstrated a colorimetric readout of Hg(II) ion through visible-light-induced polymerization, initiated by an Hg(II)-responsive photoredox initiator/catalyst under aerobic conditions. Thiosemicarbazide-functionalized 4â€?5â€?dibromorhodamine was synthesized as a stimuli-responsive photoredox catalyst. The rhodamine derivatives bearing thiosemicarbazide have been known as fluorogenic probes of Hg(II) ion with excellent sensitivity and selectivity. In this work, we incorporated a heavy halogen atom (i.e., Br) onto the xanthene core ring of the rhodamine derivative to improve the photoredox catalytic performance of rhodamine 6G, which exhibits a low catalytic performance, presumably due to the poor quantum yield of intersystem crossing. Thus, this photoredox catalyst led to the formation of a hydrogel with Hg(II) ion in a concentration of 10 μM, as the catalyst initiated free-radical polymerization of poly(ethylene glycol) diacrylate and N-vinylpyrrolidone with triethanolamine under visible light for 1 min.
