: In situ deprotection of S-tritylated mannosides . 5, 6, 10. and . 11. gave the respective thiols (5-SH, 6-SH, 10-SH. and . 11-SH) which were applied for the functionalisation of two different types of gold wafers: (a) plain gold and (b) maleimide-terminal SAMs on gold (in a linker to spacer ratio of 1:4).

The coupling was followed by a capping with Ac2O-DIPEA-DMF 3:0.3:96.7 for 10 min and washing with DMF (3 ( 2 min), and CH2Cl2 (3 ( 2 min). The Mtt group of the -NH2 of the lysine residue was removed by treatment with a solution of 1% TFA in CH2Cl2 (7 times). Monitoring of the deprotection was realized as described in reference 12.

It is proposed that this low yield is due to steric hindrance to the approach of the catalyst by the bulky trityl protecting group. The deprotection of the acetal was not attempted by usual aqueous acid hydrolysis17 due to the presence of the acid labile triethylsilylperoxy group. Tanemura et al. reported in 1992 the successful hydrolysis of ...

This isomer ratio was only slightly affected after further trityl deprotection with ZnBr2 (1:2.6-mixture of isomers . 12b. and . 13b). Identification of each isomer was based on the multiplicity ...

The selective TBS-group deprotection of 35 was followed by two step reaction protocol- oxidation and Wittig olefination with a stabilized ylide Ph3P=CHCO2Et to provide the α,β-unsaturated ester 36 exclusively in trans geometry. Next the reduction of ester functionality with DIBAL-H and TBAF mediated TIPS deprotection gave the diol 37.

The use of such protection/deprotection methods is also within the skill in the art. For a general description of protecting groups and their use, see T.W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991.
