Although, in particular cases and under specific conditions, it is possible to obtain aldofuranose peresters by direct acylation of the free sugars', it is more common to make them by strategies which restrict the products to the five-membered ring forms.

Stereospecific 1,2-rearrangement of cyclopropyl group is described as an efficient route to stereo-defined a-cyclopropyl ketones and cr-cyclopropyl aldols. Acceleration of the reaction by the introduction of trimethylsilyl (TMS) group to the a-position of cyclopropyl group is also noted. ## Cyclop
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
