[6] Introduction of uracil by the Vꢀrbruggen method following the
construction of the ribosyl diazepanone was reported to have
some drawbacks.[5a]
[7] During the course of our synthetic studies on nucleoside
antibiotics, it was revealed that the introduction of a protecting
group or substituent on this type of alcohol was quite difficult: S.

[11] The stereochemistry of the 5’ position of 5 was determined to be
the R configuration by the modified Mosher method with the
amide derivatives, which were prepared by deprotection of the
Cbz protecting group of 5 and subsequent acylation of the
liberated amine with 2-methoxy-2-trifluoromethylphenylacetic
acid (see the Supporting Information); T. Kusumi, T. Fukushima,

[15] The stereochemistry of the 1’’ position was confirmed by the
NOESY correlations between 1’’-H and 4’’-H for the b-riboside
and by the typical coupling constant (J1,2 = 0 Hz) for a 2,3-O-
alkylidene-protected ribofuranoside that was observed in the
1H NMR spectrum.
