Arsenocholine from anaerobic decomposition of a trimethylarsonioriboside

Abstract
When subjected to conditions supporting anaerobic microbial activity, the naturally occurring trimethylarsonioriboside, (2′S)‐2′‐hydroxy‐3′‐(sulpho‐oxy)propyl 5‐deoxy‐5‐trimethylarsonio‐β‐D‐riboside 4 was converted to arsenocholine 5 in virtually quantitative yield.
