A simple and efficient method for the one-pot three-component synthesis of new spirooxindoles in room temperature is described. The newly synthesized spirooxindoles were screened for anti-microbial activity and the results are good on comparison with of standard antibacterial compounds. (C) 2010 Elsevier Ltd.

l-Proline catalyzed facile and efficient synthesis of functionalized indol-3-yl pyran derivatives by multi-component reactions
A simple and green synthetic method for preparation of functionalized indol-3-yl pyran derivatives was developed. The reactions were carried out by one-pot three-component synthesis of 3-cyanoacetyl indoles, malononitrile/cyanoacetate and various aldehydes/isatins/acenaphthenequinone in the presence of catalytic amount of l-proline. The advantages of this method included straightforward processing
