Alcohols from ynals

Ynals can be selectively hydrosilylated in the presence of Pt salts leading to a-triethylsilyl enals, which undergo 1,2-addition of Grignard reagents followed by Peterson elimination from the intermediate alcohol. This method offers a simple synthetic route from ynals to the corresponding allenes.267... [Pg.64]

The tin(ll) enolate is generated from the ethyl iV-tosylglycinate/LDA/SnCl2 system and reacts with conjugated ynals and ynones to give amino alcohols in high A-diastereoselectivities (Equation (86))/... [Pg.365]
