Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides: A new method for the synthesis of γ-butanolides

A new method for the synthesis of γ-butanolides is described. The titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords the corresponding butyrolactones in 44-83% yield.

Synthesis of substituted 2,3-dihydro-1H-boroles by transmetalation of aluminacyclopent-2-enes with BF3 · Et2O

A procedure was developed for selective synthesis of 4,5-dialkyl-1-fluoro- 2, 3-dihydro-1H-boroles via transmetalation of the corresponding aluminacyclopent-2-enes with BF3 · Et2O. 4,5-Dialkyl-1-fluoro-2,3-dihydro-1H-boroles were isolated as complexes with BEtF2. 4-Alkyl-5-dimethylaminomethyl-1-fluoro-2,3- dihydro-1H-boroles were synthesized for the first time.

145. Analytic and Preparative Resolution on Racemic γ- and δ-Lactones by Chromatography on Cellulose Triacetate. Relationship between Elution Order and Absolute Configuration

Enantiomers of various chiral five- and six-membered-ring lactones, which are important classes of cpmpounds (flavour and pheromone components, key intermediates in the synthesis of biologically active substrates) have been separated chromatographically on the chiral phase cellulose triacetate, crystallographic form I (CTA I).Four different series of five-membered-ring lactones, relationships have been found between the elution order of the enantiomers and their absolute configuration.Preparative resolutions of γ-phenyl-γ-butyrolactone (1) and of the pheromone component 5b have been carried out to demonstrate the applicability of the method to g-scale separations.
