Synthesis of pseudo-sugars based on desymmetrization of dienylsilanes
摘要:
A synthesis of pseudo-sugars using the desymmetrization of a dienylsilane, followed by a stereocontrolled introduction of the hydroxymethyl group at C5. is described. The CH2OH group at C5 was elaborated using either a regioselective cyclopropane-ring opening or a [2,3]-Wittig rearrangement. (C) 1997 Elsevier Science Ltd.
