摘要：
L-Rhamnal (2) is prepared from L-rhamnose (3) by use of an improved generalized Fischer-Zach reaction. L-Rhamnal (2) is then converted to L-(-)-oleandrose (1) by stannylene mediated selective methylation and effective hydration. Benzyl alpha-L-oleandrose (12) is prepared by selective methylation and deoxygenation of L-rhamnose (3).
