摘要
Radicamine A was prepared via a key intermediate-cycle nitrone 5 by using D-arabinose as the raw material with a total yield of 15.5%.Cycle nitrone 5 was synthesized by protection of hydroxyl group,introduction of nitrogen and intromolecular cyclization.And then it had a high stereoselective addition reaction with aryl Grignard reagents 6 to form compound 7.Finally,the target compound was obtained by catalytic hydrogenation of compound 7.The novel compounds 3 and 4 were confirmed by 1HNMR,IR,MS and elemental analysis.
