A convenient synthesis of novel thiazolidin-4-one-linked pseudodisaccharides by tandem Staudinger/aza-Wittig/cyclization and their biological evaluation
Novel thiazolidin-4-one-linked pseudodisaccharides 3-6 were synthesized by the one-pot tandemStaudinger/aza-Wittig/cyclization reaction at room temperature. The deacetylation of 3-6 afforded compounds 7-10, respectively. The structures of the new compounds were determined using single crystal X-ray crystallography, (1)H, (13)C, and 2D NMR spectroscopy, and HR mass spectrometry. The preliminary biological
