A facile, efficient synthesis of 3-(guaiazulen-l-yl)succinimides was developed by Michael-type addition of guaiazulene to maleimides in the presence of p-toluenesulfonic acid under mild reaction conditions.
Two new spirostanol saponins, (25S)-spirostane-1β,3β,5β-triol 3-O-β-D-glucopyrano- side 1 and rhodeasapogenin 3-O-β-D-glucopyranosyl-(1 → 4)-β-D-glucopyranoside 2, together with a known saponin, rhodeasapogenin...
Dihydro-(2H)-1 .2.4-benzothiadizine-1. 1-dioixdes were prepared in good yields via reductive cyclization of o-nitrobenzenesulfonamidcs with aldchydes promoted by Sml2 under mild and neutral condition.
Two new compounds, isoquinoline-1, 3-dicarboxyaldehyde and (IDA) were synthesized via 6 or 7 steps starting from benzaldehyde, or prepared via 4 steps starting from allylbenzene.
The racemic spiro[4.4]nonane-1,6-dione was efficiently resolved through an enantioselective inclusion complexation using chiral host BINOL by simple recrystallization with 31 .9~38.4% yield and 1000%ee.
Fluorescene Spectra in dilute aqueous solution of a series of single chain amphiphileswith an interposed naphthalene-1,5-dioxy group were studied to elucidate the characteristic selfassembling behavior. which indicate...
Project Supported by National Sciences Foundation of China.
Ten 4-substituted bicyclic phosphates were synthesized and their ^(13)C-NMR were also determined.A good relationship was observed between 4-^(13)C chemical shift and Taft σ_X induc- tive paramenters.Substituent effec...

The electrochemi luminescence of a new reagent 6-<2-hydroxy-4-diethylaminophenylazo>-2, 3-dihydro-1, 4-phthatazine-1, 4-dione in basic aqueous solution was studied. Trace amount of silver showed significa...
2-Acetyl-5-methyl-2H-1,2,3—diaraphosphole 1 reacted with 2—butyne—1, 4—diol to form a tricoordinated phosphorus compound 7, which then rearranged to a novel 2, 3-disubstituted-1, 3-diene.Similar rearrangement has ...
