The present invention relates to a linker shown by the following formula (I):
X—SO2—R1—(A)m—R2 (I)
wherein R1 is a group of the formula (A):
[wherein R3, R4 and R5 are the same or different hydrogen, etc], etc,
R2 is a group which can form a chemical bond to a resin which may be protected by a conventional protective group,
A is lower alkylene, etc,
X is a leaving group, and
m is an integer of 0 or 1,
with proviso that A is (C2-C6)alkylene, and
m is an integer of 1,
when R1 is a group of the formula (A).
本发明涉及以下式(I)所示的连接剂:
X—SO2—R1—(A)m—R2 (I)
其中R1是式(A)的一个基团:
【其中R3、R4和R5相同或不同为氢等】等,
R2是一个可以与树脂形成化学键的基团,该树脂可能由传统的保护基团保护,
A是低碳烷基等,
X是一个脱离基团,且
m是0或1的整数,
在A为(C2-C6)碳烷基的情况下,
m是1的整数,
当R1是式(A)的一个基团。
