13C NMR signals were assigned for a series of C-6 rnethylated steroids related to 5 acholestane, and the substituent effect of methyl groups at C-6 on the shielding data is discussed.
## Abstract The PFT ^13^C NMR spectra of some representative 1โazirines are discussed. Two striking features are the large ^13^C๏ฃฟ^1^H spin coupling constants and the diagnostic chemical shift of C~3~.
## Abstract Carbonโ13 signal assignments of the labdane diterpenoids phlogantholideโA, its diacetate and isophlogantholideโA are reported. The assignments of the ^13^C NMR signals of 14โdeoxyandrographolide and its diacetate, made earlier, have now been confirmed by lanthanide shift studies on the
