  Preparation of α-substituted γ-alkoxyallylstannanes from β-tributylstannyl acrolein acetals: scope of the method and primary rationalization of the obtained results

  摘要：

  alpha-Substituted gamma-alkoxyallylstannanes were obtained from beta-tributylstannyl acrolein acetals when reacted with lower order magnesium cyanocuprates in the presence of boron trifluoride at low temperature. In the case of n-alkylcyanocuprates an anti S(N)2' substitution on a cisoid conformation appears to be the main reaction pathway. However, subtle competitions with other mechanisms may occur depending on the experimental conditions, on the reagents or on the substrates. These drawbacks constitute limitations for the use of the method especially when enantioenriched alpha-substituted gamma-alkoxyallylstannanes are desired. (C) 2004 Elsevier B.V. All rights reserved.

  γ-苄氧基烯丙基烯烃与亚环己基甘油醛的反应活性

  摘要：

  在三氟化硼的存在下，通过烷基氰基戊酸酯与3,3-二苄氧基-1-三丁基锡烷基丙-1-烯的S N 2'反应，以50-80％的产率获得苄氧基烯丙基三丁基锡。他们在不同的路易斯酸存在下与亚环己基甘油醛反应，并通过与真实的醛糖苷酶比较，在臭氧分解/脱保护序列后明确鉴定了所获得的非对映异构体加合物。简要讨论了机理以及试剂构型与烯丙基锡化反应选择性的关系。

  yield by SN2′ reaction of alkyl-cyanocuprates with 3,3-dibenzyloxy-1-tributylstannylprop-1-ene in the presence of boron trifluoride. They reacted with cyclohexylidene glyceraldehyde in the presence of different Lewis acids and the obtained diastereomeric adducts were unambiguously identified after an ozonolysis/deprotection sequence by comparison with authentic aldopentoses. The mechanisms are briefly
