Recently I am researching about Z ISOMERIZATION; ATOM ECONOMY; IONIC LIQUID; COUMARINS; BIOSYNTHESIS; DERIVATIVES; ALKYNOATES, Saw an article supported by the WWU Munster; CiM-IMPRS Graduate School. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Nevesely, T; Daniliuc, CG; Gilmour, R. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol. HPLC of Formula: C7H5F3O
An operationally simple one-pot protocol has been developed to enable the conversion of diversely substituted cinnamic acid derivatives into angularly-fused dihydrocoumarins (up to 94%). Inspired by coumarin biosynthesis, this reaction cascade harnesses photochemical E -> Z alkene isomerization enabled by energy transfer catalysis using inexpensive thioxanthen-9-one (TX) under irradiation at 402 nm. Subsequent lactonization generates the heterocyclic core prior to a second photosensitization event to induce a [2 + 2] cycloaddition, again mediated by TX. The tetracyclic products are generated efficiently, and proof of the structure was established by X-ray crystallography. Mechanistic investigations, including structural probes and NMR reaction monitoring, support the postulated order of events. The study underscores the synthetic value of inexpensive small-molecule organic photocatalysts in the generation of structural complexity via sequential pi-bond activation.
