โœฆ Synopsis

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.

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.

## Abstract The value of several reagents capable of removing quantitatively the ฮฑโ€amino protecting group of NPSโ€aminoacylโ€ or peptidylโ€derivatives is assessed, by comparison with the reagents currently used, __i.e.__ hydrogen chloride, RS^โ€“^โ€nucleophiles or alkyl thioamides, especially with regard
