Abstract
R. R. WILLIAMS has just published1 a note on the structure of aneurin (vitamin B1). From a study of degradation products of the vitamin, he concludes that his original formula (I)2 for aneurin is wrong, and that it should be represented by (II: where R1 = CH3; R2 = H); this new structure is similar in essentials to that suggested on theoretical grounds by K. Makino and T. I. Imai (II: where R1 = H; R2 = CH3)3.
