A metal-free dyotropic-like rearrangement of 2-oxa allylic alcohols in the presence of organoboronic acids†
Abstract
The first example of a dyotropic-like rearrangement of 2-oxa allylic alcohols in the presence of catalytic amounts of Selectfluor and DABCO was reported, which provides a facile access to organoboronates. This reaction represents an unprecedented dyotropic rearrangement consisting of cleavage of two vicinal bonds (one C–C bond and one CC bond).
