2-Allyloxy-1,2-oxaborolane (V), readily obtained by hydroboration of allyl alcohol with borane reagents such as KBH4-HOAc, was used as a key reactant in the synthesis of a series of 2-oxygen derivatives of 1,2-oxaborolane. 2-Allyl-1,2-oxaborolane (XXIII) and 2-hydro-1,2-oxaborolane dimethylsulfide complex (XXIV), prepared from the reaction of V with allylmagnesium bromide and dimethylsulfideborane complex (BMS) respectively, were also used as the reactive intermediates for some of the lower 2-alkyloxy-1,2-oxaborolanes.Five procedures and other probable routes from V to 2-oxygen derivatives of 1,2-oxaborolane are described.
