K. Eger et al., STERIC FIXATION OF BROMOVINYLURACIL - SYNTHESIS OF FURO[2,3-D]PYRIMIDINE NUCLEOSIDES, Journal of heterocyclic chemistry, 32(1), 1995, pp. 211-218
A new synthetic procedure for the preparation of 5,6-dihydrofuro[2,3-d
]pyrimidin-2(3H)-one (3) and its deoxyriboside 8 is reported. Compound
3 undergoes nucleophilic reactions with various agents to yield 5-sub
stituted uracil derivatives. The dehydro derivative of 3, furo[2,3-d]p
yrimidin-2(3H)-one (18) was synthesized by cyclization of BVU 15, whic
h made us develop a reproducible and high yield method for the synthes
is of BV(D)U. Starting from 18, the alpha-deoxyriboside 20 and the bet
a-riboside 22 were prepared.
