Qi, Dan published the artcilePhotoinduced synthesis of functionalized oxetanes via diradical-mediated ring contraction, Safety of 4-Methoxyphenylacetic acid, the main research area is aryl diazoacetate dihydrofuran photochem diastereoselective ring contraction; ethenyl aryl oxetane carboxylate preparation.
A versatile photochem. ring contraction was reported for the synthesis of oxetanes under catalyst-free conditions. The reaction was enabled by the use of 2,5-dihydrofurans and diazo compounds under visible light irradiation, delivering functionalized 3-vinyloxetanes as major products. The outstanding features of this protocol included mild reaction conditions, operational simplicity and scalability, as well as excellent functional-group tolerance. DFT calculations indicated that the reaction may proceed through the formation of an oxonium ylide intermediate followed by a diradical-mediated rearrangement and cyclization.
Green Chemistry published new progress about Diastereoselective synthesis. 104-01-8 belongs to class isoquinoline, name is 4-Methoxyphenylacetic acid, and the molecular formula is C9H10O3, Safety of 4-Methoxyphenylacetic acid.
