I found solution with using 'word' and 'wordlist'
(note that file MUST lies in same depth):

empty =
space = $(empty) $(empty)

var = dir1/a/b.txt dir2/c/d.txt

newvar = $(foreach item,$(var),$(subst $(space),/,$(wordlist 1,2,$(subst 
/,$(space),$(item))))/newdir/$(word 3,$(subst /, ,$(item))))

all:
        echo $(newvar)

But any time you can use $(shell sed ......)  :)
