The isomerically pure Z- and E-pentenylboronates 2 and 3 were added to ketones under 4 to 8 kbar pressure resulting in the homoallyl alcohols 10 - 13 with different diastereoselectivities.These reactions were considered as models for the addition of other Z- and E-pentenylmetal compounds to ketones.The diastereoselectivities obtained tn the addition of configurationally undefined pentenyl Grignard (4) and titanium reagents (5,6) is discussed against this background.
