Deprotection of 1,3-oxathiolanes to ketones promoted by base
摘要:
A variety of 1,3-oxathiolanes can be easily converted to the corresponding ketones in good yields with LTMP in THF. This deprotection methodology shows satisfactory chemoselectivity when other protecting groups, such as dimethylketal, 1,3-dioxolane, 1,3-dithiane, and other acid-sensitive groups, are present within the same substrates.
