<p>PROBLEM TO BE SOLVED: To provide a protective group which inhibits the dissolution of a protector in a water layer side and allows protectors to be obtained with good yields.SOLUTION: This invention relates to a protective group of a functional group used for an organic synthesis method, the protective group represented by general formula (1), an organic synthesis method using the protective group, a protective group introduction method and a protector. (In the general formula (1), Rto Rindependently represent a hydrogen atom or an alkyl group having 5 or less carbon atoms, and at least one of Rto Rrepresents an alkyl group having 5 or less carbon atoms.)</p> |
