A Lewis acid-catalyzed nucleophilic addition of electron rich aromatics with 3-hydroxy-2-oxindoles 5 was developed. The reaction is believed to proceed through the 2H-indol-2-one ring system 9, which eventually reacts with various electron-rich aromatics to afford a variety of 2-oxindoles with an all-carbon quaternary center at the pseudobenzylic position(More)
The goal of waveform shaping techniques in orthogonal frequency division multiplexing systems is reduction in out of band (OOB) transmit power as well as reduction in inter-carrier interference (ICI) generated by carrier frequency offset at the receiver. We propose waveform shaping using a linear combination of time-limited polynomial pulses having spectral(More)
