Abstract
The simple syntheses of L-fucopyranose 1 and its three analogues 2-4 a re described. A key reaction is a stereocontrolled elongation by one c arbon unit at the side chain of an alpha-D-arabino-pentodialdo-1,4-fur anoside 9 with MeMgI-ZnCl2 or Me(3)Al. Diastereofacial selectivities o f more than 92% were achieved.
