Abstract
High-pressure (4+2)cycloaddition of 1-methoxybuta-1,3-diene ( 1 to 2,3-O-isopropylidene-D-glyceraldehyde ( 2 ) afforded four diastereoisomeric 6-substituted 2-methoxy-5,6-dihydro-2H-pyrans ( 3 ), for which the diastereoisomeric excess and absolute configuration were determined. The effects of pressure, temperature and solvent on asymmetric induction were examined. Stereochemical models were used for interpretation of the results.
