Novel cleavage of (E)-allyl vic-diols to aldehydes using the 2nd-generation Grubbs catalyst
摘要:
Secondary (E)-allyl vic-diol cleavage in the presence of the 2nd-generation Grubbs catalyst has been developed. The position of a vic-diol adjacent to C=C plays a crucial role in the cleavage reaction compared to an alkyl vic-diol based on a model compound. (C) 2008 Elsevier Ltd. All rights reserved.
Grubbs carbene complex-catalyzed cleavage of allyl vic-diols to aldehydes with a co-oxidant: application to the selective cleavage of huge marine molecules
摘要:
An oxidative cleavage of allyl vic-diols to aldehydes catalyzed by a Grubbs carbene complex using a co-oxidant has been established for the first time, with good yields. The utility of this selective cleavage reaction was demonstrated through the use of two huge marine molecules, symbiodinolide and N-p-BrBz palytoxin. (C) 2011 Elsevier Ltd. All rights reserved.
