Abstract
The ^13^C and ^1^H NMR spectra of thujopsanone oxime, 7βhaloβ7βnitrosothujopsanes, nootkatβ1βone oxime and 1βchloroβ1βnitrosonootkatane are reported.

The 1H and 13C NMR resonances of 19 tetracyclic acridinone derivatives were completely and unambiguously assigned by a combination of 1H-detected one-bond HMQC and long-range (two and three bonds) HMBC correlation experiments. 1H and 13C chemical shifts are also reported for the respective N -aryl b
The complete assignment of the 1H and 13C NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradientselected correlation experiments.
## Reference Data and chemical shifts of some tetracyclic and 1H 13C pentacyclic acridinone derivatives
The 1 H and 13 C NMR chemical shifts of 16 4,5disubstituted acridine derivatives and nine 4-substituted-5,5 0 (Λ0 0 ,Ο 00diaminoacyl)bisacridine derivatives are reported. Chemical shift assignments were established from 1D and gradient-enhanced 2D measurements.
## Abstract A series of areneboronic acids were studied by NMR spectroscopy. Increments for the ^1^H and ^13^C chemical shifts caused by the boronic acid substituent B(OH)~2~ in areneboronic acids were determined. Copyright Β© 2003 John Wiley & Sons, Ltd.
