Abstract

The ^13^C NMR spectral assignments and ^1^J(C,H) spin–spin coupling constants for methyl 4‐anilino‐3‐nitrobenzoate, methyl 4‐p‐chloroanilino‐3‐nitrobenzoate, methyl 4‐p‐toluidino‐3‐nitrobenzoate, methyl 4‐p‐ anisidino‐3‐nitrobenzoate, methyl 4‐hydroxy‐ 3‐methoxybenzoate and methyl 3,4‐dimethoxybenzoate are reported.

## Abstract __J__(^13^C^1^H) coupling constants for some methyl‐ and aminopyrimidines have been determined by ^13^C NMR. Both the one‐bond and long‐bond and long‐range coupling constants follow general trends which can be summarized in a few simple rules. In particular, the ^3^__J__(C‐i,H) coupling

## Abstract A recently introduced tracer, [3,4‐^13^C~2~]glucose, was compared to the widely used tracer, [6,6‐^2^H~2~]glucose, for measurement of whole‐body glucose turnover. The rate of glucose production (GP) was measured in rats after primed infusions of [3,4‐^13^C~2~]glucose, [6,6‐^2^H~2~]gluco

## Abstract The ^13^C chemical shifts for 1,3‐dithiane and 9 methyl substituted derivatives are reported. Only three of the methyl‐1,3‐dithianes were conformationally anancomeric and hence the conformational equilibria must be taken into account when deriving the values of the different substituent
