The azidophenylselenylation of 3,4,6-tri-O-acetyl-d-galactal provides straightforward access to the corresponding 2-nitrogenated glycoside. Poor reproducibility and the use of azides that lead to the formation of potentially explosive and toxic species limit the scalability of this reaction and render it a bottleneck for carbohydrate synthesis. Here, we present a method for the safe, efficient, and reliable azidophenylselenylation of 3,4,6-tri-O-acetyl-d-galactal at room temperature, using continuous flow chemistry. Careful analysis of the transformation resulted in reaction conditions that produce minimal side products while the reaction time was reduced drastically when compared to batch reactions. The flow setup is readily scalable to process 5 mmol of galactal in 3 h, producing 1.2 mmol/h of product."}],"publication":"Organic Process Research and Development","publication_status":"published","doi":"10.1021/acs.oprd.9b00456","author":[{"first_name":"Mónica","full_name":"Guberman, Mónica","last_name":"Guberman"},{"orcid":"0000-0001-8689-388X","first_name":"Bartholomäus","full_name":"Pieber, Bartholomäus","id":"93e5e5b2-0da6-11ed-8a41-af589a024726","last_name":"Pieber"},{"first_name":"Peter H.","full_name":"Seeberger, Peter H.","last_name":"Seeberger"}],"_id":"11984","date_created":"2022-08-25T11:30:33Z","month":"12","citation":{"ista":"Guberman M, Pieber B, Seeberger PH. 2019.
