2-Arylallyl as a New Protecting Group for Amines, Amides and Alcohols. —
novel protecting group 2-arylallyl for amines, amides and alcohols is developed. The
27- 063 A
protected compounds are selectively and easily deprotected with tBuLi, even in the
presence of other allyl-protected functionalities. The mechanism of the cleavage reaction probably involves an intermolecular carbolithiation of the styrenyl moiety followed by a spontaneous β-elimination process. — (BARLUENGA*, J.; FANANAS,
