  Synthesis of isofagomine has been achieved by implementation of aza-Claisen rearrangement of 2-C-hydroxymethyl glycals as a key step. The above rearrangement has also been utilized in the synthesis of biologically important polyhydroxylated piperidine frameworks such as isogalactofagomine, ent-isogalactofagomine and their analogues and some other azasugars as glycosidase inhibitors.

  通过实施2- C-羟甲基糖的氮杂-克莱森重排作为关键步骤，已经实现了异黄酮的合成。上述重排也已用于合成生物学上重要的多羟基哌啶骨架，例如异半乳糖胺，对-异半乳糖胺及其类似物和一些其他的作为糖苷酶抑制剂的氮杂糖。

  This paper describes the substrate specificity and synthetic utility of deoxyribose-5-phosphate aldolase (DERA, EC 4.1.2.4). Eight donors and 20 acceptors have been tested as substrates. In addition to acetaldehyde, propanal, acetone, and fluoroacetone have been used to condense with a number of acceptor aldehydes. Thirteen aldol products have been prepared and characterized. A new stereogenic center with 3(S) configuration is formed when acetaldehyde, fluoroacetone, or acetone is used as a donor substrate. With propanal, two new stereogenic centers are formed with 2(R) and 3(S) configurations. The acceptor substrates have very little structural requirements. The 2-hydroxyaldehydes appear to react the fastest, and the D-isomers are better substrates than the L-isomers. The stereospecificity is absolute regardless of the chirality of 2-hydroxyaldehydes. The aldol reactions thus follow the Cram-Felkin mode of attack for D-substrates and anti-Cram-Felkin mode of attack for L-substrates.
