A mild deprotection strategy for allyl ethers under basic conditions in the presence of a palladium catalyst is described. Under these conditions, aryl allyl ethers can be cleaved selectively in the presence of alkyl allyl ethers. These conditions are also effective in the deprotection of allyloxycarbonyl groups. The utility of the current methodology in sequence specific dendrimer synthesis is demonstrated
描述了在碱性条件下在钯催化剂存在下对烯丙基醚的温和脱保护策略。在这些条件下,可以在烷基烯丙基醚的存在下选择性地裂解芳基烯丙基醚。这些条件对于烯丙氧羰基的脱保护也是有效的。证明了当前方法在序列特异性树状聚合物合成中的实用性。
