  • The synthesis of novel taxol analogues with an amine moiety at the 7- and 10-positions to examine the BBB penetration was described. The analogues were synthesized from 2'-O-(tert-butyldim-ethylsilyl)taxol and 2'-0-(tert-butyldimethylsilyl) -7-O-(triethylsilyl)-10-deacetyltaxol, the key intermediates, in 2 steps via the esterification with heterocyclic amino acids and the subsequent desilylation reaction.

  • Enzymatic resolution is becoming increasingly important in the production of optically active pharmaceutical drugs and is now challenging the traditional synthetic methods for production of a variety of chiral intermediates and products. This article reviews the recent advances in chirotechnology using enzymes as a catalyst to resolve chiral compounds. The review focuses on the recent trends in chirotechnology and the application of enzymes to the production of industrially valuable pharmaceutical drugs.
