Abstract

'Concentration of substrate, TMSN, and Lewis acid is 0.017, 0.051, and 0.10 mmol, respectively. o/p ratio is calculated as fol-lows. bo/p= I (yield)/g (yield)= 8/9.'o/p= 9/10. d~/~= 11/12.'o/p= 13/14. fo/p= 15/16. 8o/p= 17/18. substrates possess a side chain that has several arranged oxygen atoms, the question arises whether nitronium ions might be collected along the chain symbolized in A, for the
