Abstract
Still-Gennari reactions have been carried out on a range of E- and Z-3-substituted propenals. In all cases, with the exception of Z-3-stannyl systems, good Z-stereoselectivity was observed. By contrast, the Ando procedure gives reasonable Z-stereoselectivity with all systems studied, including those with a cis-disposed stannyl substituent. © 2003 Elsevier Ltd. All rights reserved.
