  摘要：

  Epoxidation of cis-3,4-bis(benzyloxymethyl)cyclobut-1-ene 4 gave compounds 7a and 7b which were separated Reaction of the cis-epoxide 7a with adenine led to the N-9 and N-7 attack products, 10a and 10b, respectively. In the same conditions, the trans-epoxide 7b yielded the N-9 product 12. Nucleoside analogues 11 and 13 were obtained by debenzylation of 10a and 12, respectively.

  Epoxidation of 2, 3, 4 with m-CPBA mainly led to the cis-attack products whereas 1 and 6 led to the other selectivity. The result was reversed, from 4, with Payne's reagent Bromohydroxylation of 4 involved an intermediate bromonium ion syn to the substituents. Haloselenylations occurred with the syn-selectivity from 1, 2, 3 and 4, to the anti-selectivity from 6, and without selectivity from 5. NOE enhancement measurements and several chemical correlations led to the stereochemical assignments. Formation of the intramolecular reaction products 24 and 25 was also pointed out.

  Cis-3,4-bis(benzyloxymethyl)cyclobut-1-ene 1 mainly led to bromohydrin 5 with a cis relationship between bromine and the benzyloxymethyl groups. The stereospecific ring contraction of 5 afforded aldehyde 7 which could be converted into the nucleoside analogue 1 2.
