What is Stereoselective allylation for preparation of L-hexose derivatives about?
The reaction of allyltrimethylsilane with CC, pdialkoxyaldehydes is catalyzed by magnesium bromide, and provides for a highly stereoselective allylation which is predicted by a-chelation of the Lewis acid. The observed stereocontrol is opposite to that generally obtained from a variety of common allylation reagents. Ox recent synthetic investigations have required a versatile and convenient preparation of L-hexoses. Furthermore, these efforts required appropriate protecting units for hydroxyl differentiation. We wish to report a study of stereoselectivity in the allylation of the m @-dialkoxyaldehydes 1\_ and 2, which affords access to a series of rare L-monosaccarides. 1
