Abstract
[GRAPHICS] Rh-2(R-DOSP)(4)-catalyzed decomposition of methyl aryldiazoacetate in the p resence of allyl silyl ethers results in a regioselective C-H insertion; Th e resulting beta-siloxy esters are formed with high enantioselectivity (74- 92% ee) and diastereoselectivity (96-98% de) when trans-disubstituted allyl silyl ethers are used as substrates.
