A short and concise synthesis of isofagomine, homoisofagomine, and 5′-deoxyisofagomine
摘要:
A short and concise synthesis of isofagomine derivatives via the epoxidation of chiral N-Boc-5-hydroxy-3-piperidene, followed by regioselective epoxide ring opening is described. This constitutes the first reported synthesis of homoisofagomine and the 5'-deoxyisofagomine. (C) 2004 Elsevier Ltd. All rights reserved.

for the synthesis of a variety of 1-azasugars with a nitrogen atom at the anomeric position is described. The readily available chiral N-Boc-5-hydroxy-3-piperidene 3 is transformed to isofagomine (2), homoisofagomine (13), and 5‘-deoxyisofagomine (14) via stereoselective epoxidation and regioselective ring-cleavage in a highlystereocontrolled manner. In addition, the synthesis of all four stereoisomers
