A MET-OH derivative,MET-OTs 1,was designed,prepared and structurally charac-terized by single-crystal X-ray diffraction. X-ray structure analysis reveals that 1 crystallizes in the monoclinic system,space group P21/c,with a=16.1178(14),b=7.5473(6),c=13.4161(11),V= 1520.3(2)3,β=111.3210(10)o,Z=4,Dc=1.421 g/cm3 and F(000)=680.
