Specification
WE CLAIM:
1. A method for protecting a 1,2-diol group or a 1,3-diol group, comprising reacting a 1,2-diol group or a 1,3-diol group with a group represented by Formula (19) in the presence of a base,
(in the formula, Rla and Rlb are the same as or different from each other and each represent a hydrogen atom or a carboxy protective group; and * is a binding position).
2. A method for protecting a 1,2-diol group or a 1,3-diol group, comprising manufacturing a compound represented by Formula (21) by reacting a 1,2-diol group or a 1,3-diol group of a compound represented by Formula (20) with a compound represented by Formula (9) in the presence of a base,
HO-Y1-OH (20) (in the formula, Y is a C2-3 alkylene group which may be substituted),
(in the formula, each of Rla and Rlb are the same as or different from each other and each represent a hydrogen atom or a carboxy protective group; and R6 is a C1-6 alkyl group which may be substituted), and
(in the formula, each of Rla, Rlb, and Y1 has the same definition as described above).
3. A method for deprotecting a protected 1,2-diol group or 1,3-diol group, comprising reacting a 1,2-diol group or a 1,3-diol group protected with a group represented by Formula (19) with a base,
(in the formula, Rla and Rlb are the same as or different from each other and each represent a hydrogen atom or a carboxy protective group; and * is a binding position).
4. A method for deprotecting a protected 1,2-diol group or 1,3-diol group, comprising manufacturing a compound represented by Formula (20) by reacting a compound which is represented by Formula (21) and has a protected 1,2-diol group or a protected 1,3-diol group with a base,
(in the formula, Rla and Rlb are the same as or different from each other and each represent a hydrogen atom or a carboxy protective group; and Y is a C2-3 alkylene group which may be substituted), and
IH0-Y1«0H (20)
(in the formula, Y1 has the same definition as described above).
