The effect of trifluoroacetic acid on the endocyclic cleavage of ethyl 1-thio-β-d-manno-, gluco-, galacto- and β-l-fucopyranosides with bulky silyl groups
{{output}}
Earlier we found that the treatment of ethyl 1-thio-β-d-galactopyranoside containing triisopropylsilyl (TIPS) groups at O-2 and O-3 with TFA-CH2Cl2 led to the corresponding 2,3-bis-O-silylated 1-thio-d-galactofuranoside. However, when ethyl 1-thio-β-d-glucop... ...
