Double Reduction of Cyclic Aromatic Sulfonamides: A Novel Method for the Synthesis of 2- and 3-Aryl-Substituted Cyclic Amines
摘要:
The facile double reduction of bicyclic aromatic sulfonamides was used to synthesize a variety of 2- and 3-aryl-substituted pyrrolidines and 2-phenylpiperidine. The method features a combined nitrogen protection and a traceless tether for the transposition of the aromatic moiety from nitrogen to carbon.

1-Aryl-1,2,3,4-tetradeoxy-1,4-imino-D-pentitols 5 and 9f are easily synthesized from N-Boc-L-pyroglutamate 1 via a successive procedure involving regioselective ring-opening, recyclization with dehydration, stereoselective reduction, and reduction of the ester group. Their structures are determined mainly by X-ray crystallography and NMR measurements. Their bioassay is also described.
