## Abstract We report the total assignments of the ^13^C and ^1^H NMR spectra of some 4βmethylβ2βoxoβ(2__H__)βpyrido[1,2β__a__]pyrimidine and 2βmethylβ4βoxoβ(4__H__)βpyrido[1,2β__a__]pyrimidine derivatives. The products were characterized by ^1^H and ^13^C NMR and reported data for similar compound

Abstract
Fucose is believed to be a marker for cancer that may be detectable by the 2D proton NMR (COSY) of human plasma. However, the COSY technique is time consuming and prone to error. These problems may be alleviated by using the SUPERCOSY pulse sequence; this technique shows that there are many other cross peaks in the region (1.3, 4.2 ppm) which are not readily distinguishable from fucose.

Three known bisabolane hydrocarbons, a-trans -bergamotene, sesquiphellandrene and zingiberene, were isolated from the aerial parts of Alpinia densibracteata . Their 1H and 13C NMR spectra were completely assigned by using a combination of 13C DEPT and 2D-NMR experiments (1H-1H COSY, single-bond 13C-
The 1H and 13C NMR spectra of glucodigifucoside and glucogitoroside, cardenolides isolated from Digitalis lanata leaves, were completely assigned with the aid of 2D homonuclear (COSY) and heteronuclear (HETCOR and HMQC) correlation spectra. 1997
