Schmidt reactions diastereoselectivities

Also propiogeninic type macrolide moieties should be accessible via this inverse type hetero-Diels-Alder methodology. This was recently exhibited starting from cis-propenylether as heterodienophile (Schmidt, R.R. Haag-Zeino, B. Hoch, M. Liebigs Ann. Chem., in press). In a highly endo-selective cycloaddition reaction and in subsequent diastereoselective transformations of the methyl substituted dihydropyran obtained a 2,4-dimethyl-... [Pg.190]
