<p>PROBLEM TO BE SOLVED: To provide a new oxazoline compound usable for the synthesis of a taxane compound having a side chain and provide a method for the production of the oxazoline compound. SOLUTION: The oxazoline compound is expressed by formula I (R<1> is R<5> , R<7> -O, R<7> -S or (R<5> )(R<6> )N; R<2> is R<7> -O, R<7> -S or (R<5> )(R<6> )N; R<3> and R<4> are each R<5> , R<5> -O-C(O) or (R<5> )(R<6> )N-C(O); R<5> and R<6> are each hydrogen atom, an alkyl, an alkenyl, an alkynyl, a cycloalkyl, a cycloalkenyl, an aryl or a heterocyclic group; and R<7> is an alkyl, an alkenyl, an alkynyl, a cycloalkyl, a cycloalkenyl, an aryl or a heterocyclic group) or its salt.</p> |
