Dioxygenase-catalysed dihydroxylation of arene cis-dihydrodiols and acetonide derivatives: a new approach to the synthesis of enantiopure tetraoxygenated bioproducts from arenes
Chemical synthesis of optically active cis-cyclohexa-3,5-diene-1,2-diols and their 5-2H-derivatives
摘要:
A variety of optically active 3-substituted cis-cyclohexane-3,5-dien-1,2-diol acetonides were readily prepared from chiral 5-(tert-butyldimethylsilyloxy)-2-cyclohexenone through a seven-step reaction in good overall yield. The synthesis also allowed preparation of the acetonide having an H-2-atom at the 5-position. (C) 2001 Elsevier Science Ltd. All rights reserved.
