Development of a speech analyser/synthesizer for special applications in linguistics
This project on the development of a speech analyzer/synthesiser for special applications in linguistics was proposed for the purpose of developing computer software for the alteration of the prosodic characteristics of speech signals in the English Language.RP 12/8

ADS thanks the Royal Society for a Wolfson Research Merit AwardThe catalytic enantioselective 6-exo-trig Michael addition-lactonization of enone-acid substrates to form cis-chromenones with high diastereo- and enantiocontrol was developed using the commercially available isothiourea tetramisole. An acidic workup proved necessary to minimize product epimerization and maximize product er, providing cis-chromenones in excellent yield, and with excellent diastereo- and enantioselectivity.Publisher PDFPeer reviewe
