Chemoenzymatic synthesis of rengyoside -A, -B, isorengyoside and synthesis of their aglycones
摘要:
The chemoenzymatic synthesis of a group of naturally occurring cyclohexylethanoids, rengyoside-A, -B and isorengyoside, has been performed by enzymatic glucosidation of their chemically synthesized aglycones, rengyol, rengyoxide and isorengyol. (C) 1997 Published by Elsevier Science Ltd.

Pyrano[4,3-b]indole derivatives as alpha-1-antitrypsin modulators for treating alpha-1-antitrypsin deficiency (AATD)
A selective and practical approach for the formation of cis-1,4-aminocyclohexanol was developed. The key transformation involves a one-pot imine formation/ Lewis acid-directed imine reduction and results in a highly selective attack of the reducing agent. This simple and practical method is easily amenable to large-scale synthesis. (C) 2010 Elsevier Ltd. All rights reserved.

An experimental protocol demonstrating the protection of the carbonylgroup as 1,2,4-trioxane, the stability of the protecting group under a variety of reaction conditions, and the regeneration of the carbonylgroup with Triton B in THF at room temperature is presented. The method provides a useful alternative for the protection of carbonyl compounds having acid-sensitive moieties.
