2 ne pot synthesis of 4-(arylidene)-2-[5-(4-hydroxy-6- methyl-2-oxo-2-pyran-3-yl)-thiazol-2-yl]-5-methyl- 2,4-dihydro-pyrazol-3-ones via multi-component approach An efficient, one pot, four-component approach for the synthesis of 4-(arylidene)-2-[5-(4-hydroxy-6-methyl-2-oxo-2-pyran-3-yl)-thiazol-2-yl]-5-methyl-2,4-dihydropyrazol-3-ones has been described. This synthesis involves the simultaneous formation of thiazole and pyrazole ring systems followed by condensation of different aldehydes on active methylene group of pyrazolone under Knoevenagel reaction conditions.

5 1235 otes 1284 Lupane-triterpenoids from stem bark of Dillenia indica From the methanol extract of the stem bark of Dillenia indica, one new triterpene acid ester,dillenic acid 1 along with four known compounds, betulinic acid 2, 3-epi- betulinic acid 3, 3-epidihydrobetulinic acid 4 and 3α-hydroxy-lup-20(29)-en-23,28-dioic acid 5 have been isolated. tructure of the new compound 1 is elucidated on the basis of detailed spectroscopic (including 2D MR) and chemical studies. Compound 3 is reported for the first time as natural product and compounds 2 and 4 are reported for the first time from this plant.
