Two simple procedures for obtaining (Z)-2-(1-trimethylsilyl-1-alkenyl)-1,3,2-dioxaborinanes based on 1-trimethylsilyl-1-alkynes are described. In the first procedure, 1-trimethylsilyl-1-alkynes are hydroborated with diisopinocampheylborane to provide the corresponding (Z)-2-(trimethylsilyl-1-alkenyl
A convenient, novel synthesis of alkyl cyclopropyl ketones based on Z-1-bromo-1-alkenylboronate esters is developed. a-Bromo-(Z)-1-alkenylboronate esters readily available from literature procedures smoothly undergo a reaction with cyclopropylmagnesium bromide in tetrahydrofuran to provide the corre
