title: Rapid and versatile synthesis of functionalized polyhydroxylated fragments.
abstract: [reaction: see text] The condensation between a functionalized allylstannane and alpha-alkoxyaldehydes allows rapid access to complex and selectively protected trihydroxylated synthons. The stereocontrol of this process is strongly dependent upon the nature and the amount of the Lewis acid employed.
