Abstract
SINIGRIN is a crystalline thioglucoside, extracted first by Bussy1 from the seeds of black mustard. It is the potassium salt of the anion [C10H16O9NS2]−, also called the myronate ion, and the crystals contain one molecule of water per potassium ion. In 1897 Gadamer2 proposed formula (I) for the myronate ion. Schneider and collaborators confirmed the thioglycoside linkage in 1914 (ref. 3) and in 1930 (ref. 4) established that sinigrin and analogous glucosides are 1-β-D-thio-glucosides. Important details of the Gadamer formula I were challenged recently by Ettlinger and Lundeen5, who have advanced convincing arguments in favour of structure II, with the sugar in the β-gluco-pyranoside form. While Schultz and Wagner6 cast some doubt on II, on the basis of infra-red work, the synthesis by Ettlinger and Lundeen7 of the closely related glucotropaeolate ion (allyl replaced by benzyl) strongly affirmed the correctness of II. Ettlinger and Lundeen advanced arguments based on reaction mechanisms that suggest a syn configuration of sulphate and thioglucose relative to the C=N double bond. However, these arguments were inconclusive8,9. The chemistry of sinigrin and related compounds as well as their biological properties have been reviewed recently10.
