Crude Chicken Liver Esterase Mediated Resolution of Homoallyl Alcohols
摘要:
Racemic acetates of homoallyl alcohols have been enantio-selectively hydrolyzed by crude chicken liver esterase (liver acetone powder) to provide homoallyl alcohols in 72-98% optical purities.
to be an efficient catalyst for allylation and cyanation of aldehydes with allyltrimethylsilane and trimethylsilyl cyanide in the presence of aceticanhydride at room temperature to produce homoallylic acetates and α-cyano acetates in excellent yields. A solution of 10 mol % of LiBF4 in acetonitrile provides a convenient reaction medium to carry out allylation and cyanation reactions under very mild
