Indium-mediated allylation of aldehydes with 2-chloro-3-iodopropene, followed by a palladium-catalyzed cross-coupling reaction with triarylindium reagents or arylboronic acids, leads to aryl-substituted homoallylic alcohols in good to excellent yields and diastereoselectivities. The products obtained from reactions conducted with D-glyceraldehyde acetonide can be transformed into 2-deoxy-β-C-aryl ribofuranosides in high overall yields. Similarly, 2-deoxy-β-C-aryl allopyranosides may be prepared efficiently from 2,4-O-benzylidene erythrose.
