摘要
[GRAPHICS] Sequential addition of i-PrMgCl and BuLi to Sp(3) hybridized iodoalcohols triggers a facile iodine-metal exchange. Intercepting the resulting cyclic Grignard reagents with a slight excess of an electrophile leads to a diverse range of substituted alcohols. The iodine-magnesium exchange strategy is effective with 3-carbon iodoalcohols bearing alkyl substitutents on the carbinol or adjacent carbons and with the chainextended homolog 4-iodobutan-1-ol.
