Abstract
Long-range H-1-N-15 GHMQC spectra afford a viable means of beginning t o incorporate N-15 into strategies to elucidate the structures of pote ntially novel alkaloids. Long-range H-1-N-15 heteronuclear shift corre lation using a variant of the gradient-enhanced HMQC pulse sequence is demonstrated at N-15 natural abundance using the indoloquinoline alka loid cryptolepine.
