Additions , promoted by the hydroxyl' function, of Grignard reagents to alkynols were reported in two recent communications. 2,3 The configurations (cis-trans) of the hydrolysis (H replacing \_-Mg) products obtained from the vinyl Grignard reagents that result from such additions are
The high pressure (9 kbar, 3oOC) mediated addition of benzaldehyde to allylstannane (1) occurs stereospecifically with syn approach of the electrophile. At 6OoC, the reaction is less selective, probably due to some isomerization of cis (1) to trun.s (1). At both temperatures good erythro diastexeose
