The first enantioselective synthesis of (−)-microcionin 2
摘要:
An approach known to give regiospecific and stereospecific reactions has been applied to the enantioselective synthesis of the natural (-)-microcionin 2 (1), a prototype of trans relationship of the methyl groups on the furanosesquiterpenes. Copyright (C) 1996 Elsevier Science Ltd

The reduction of a series of α,β-unsaturated ketones has been studied under various experimental conditions, by using β-branched trialkylalanes. Asymmetric induction phenomena are observed when optically active trialkylalanes are used.
(1R,5R)-1-(1′-Dimethylaminoethyl)-2-isopropylidene-5-methylcyclohexanol as a Chiral Ligand in the Enantioselective Addition of Diethylzinc to Aldehydes
An efficient chiralligand, (1R,5R)-1-(1'-dimethylaminoethyl)-2-isopropylidene-5-methylcyclohexanol, has been developed for the enantioselectiveaddition of diethylzinc to some prochiral aldehydes to afford S-alcohols. The overall conversion rate was 80-98% with excellent enantiomeric excess (79-98%).
