โฆ Synopsis
The protection of the 06-amide and N2-amino groups of guanosine with the (butylthio)carbonyl group is described. This group could be rapidly introduced in good yields and removed very easily under the conventional deprotective condition for the exo-amino acyl groups of other nucleoside bases.

Symmary: Protection of the guanine residue with the 06-diphenylcarbamoyl and N -propionyl groups is described. These protecting groups could be readily introduced and removed simultaneously. They were used to demonstrate the synthesis of the deoxyguanylate dimer in high yield.
During the course of various synthetic projects under study in these Laboratories we have had occasion to devise and apply a number of new methods for the protection of hydroxyl' , carbony and la&one' functions. 4 We now wish to report some recent results on the protection of aldehydes and ketones
The 1,1,1,3,3,3-Hexafluoro-2-propyl group can be used as a new class of phosphate protecting group for the protecting group of internucleotidic bonds in the oligonucleotide synthesis by the phosphotriester approach . This protecting group is removed easily by treatment with 0 .3 M N 1 ,N 1 ,N 3 ,N''
