CMD Paper in Bioorganic & Medicinal Chemistry
Congratulations to Han Yueh, Qiwen Gao, and Professors John Porco and Aaron Beeler on their recent paper in Bioorganic & Medicinal Chemistry entitled “A photochemical flow reactor for large scale syntheses of aglain and rocaglate natural product analogues”
Abstract: Herein, we report the development of continuous flow photoreactors for large scale ESIPT-mediated [3 +2]-photocycloaddition of 2-(p-methoxyphenyl)-3-hydroxyflavone and cinnamate-derived dipolarophiles. These reactors can be efficiently numbered up to increase throughput two orders of magnitude greater than the corresponding batch reactions.
Lauren Brown and Mikayo Hayashi: Communication in the European Journal of Organic Chemistry
Congratulations to Lauren Brown, Mikayo Hayashi and Professor John Porco on their recent Communication in the European Journal of Organic Chemistry entitled "Asymmetric Dearomatization/ Cyclization Enables Access to Novel Chemotypes."
Abstract: Enantioenriched, polycyclic compounds were obtained from a simple acylphloroglucinol scaffold. Highly enantioselective dearomatization was accomplished using a Trost ligand palladium(0) complex. A computational DFT model was developed to rationalize observed enantioselectivities and revealed a key reactant-ligand hydrogen bonding interaction. Dearomatized products were used in visible light-mediated photocycloadditions and oxidative free radical cyclizations to obtain novel polycyclic chemotypes including tricyclo[4.3.1.01,4]decan-10-ones, bicyclo[3.2.1]octan-8-ones and highly-substituted cycloheptanones.
