Novel fragmentation of 3-lithio-3,6-dihydro-1,2-oxazines: Synthesis of 2,5-dihydro-2-furanylamines
摘要:
N-Cbz or N-Boc protected 3,6-dihydro-1,2-oxazines 1 on treatment with LDA at -78-degrees-C undergo a novel rearrangement to provide synthetically useful N-Cbz or N-Boc protected dihydro-2-furanylamines 2.
