R 0070
Preparation and Stereochemistry of the Isopropylidene Derivatives of
and 1,2,9,10-Tetrahydronaph19- 118 1,2-Dihydronaphtho[2,1-b]furan-1,2-diol
tho[2,1-b:7,8-b']difuran-1,2,9,10-tetraol in Comparison with the Corresponding
Acetyl Derivatives. — In the case of compound (I), only the cis-isomer (III) is
obtained. Trans isomers are not formed. In the case of compound (IV), the cis-anti-cis
isomer (V) is formed, but no cis-syn-cis isomer. In the acylation of compound (IV), the
isomeric ratios correspond to their stability. — (YAMAYE*, M.; MOTOYANAGI, Y.;
