Reaction of isopulegol and similar alcohols with sulfuryl chloride

The reaction of isopulegol with sulfuryl chloride (or chlorine) gives two types of products: on one hand 8-chlorocitronellal and 6-chloroisocitronellal both issued from a fragmentation pathway and, on the other hand 10-chloroisopulegol resulting from an allylic chlorination.The first process, the radical nature of which is demonstrated, is clearly favored by elevated temperatures while the second one is exclusive at 0 deg C.Homologous compounds such as p-mentha-1,8-dien-5-ols, 3-phenylisopulegol and isopulegone dioxolane give rise to one or both of these processes. --- Key Words: allylic chlorination / radical fragmentation

The monoterpene trans- and cis- fused α-methylene-γ-butyrolactones (1) and (2) have been synthesised from the appropriate isopulegol epimers (3) and (4).
