R-(–)-Pantolactol in the Julia–Kocienski Reaction
摘要
Abstract
The KHMDS-promoted reaction of (3R)-3-(1-ethoxyethoxy)-4,4-dimethyltetrahydrofuran-2-ol with 5-(methylsulfonyl)-1-phenyl-1H-tetrazole forms 5-{[(2S,3R)-3-(1-ethoxyethoxy)-4,4-dimethyltetrahydrofuran-2-yl]oxy}-1-phenyl-1H-tetrazole, an anomalous heteroaryl pantolactone acetal.
