Chiral-substituted 3-amino tetrahydro-2H-pyran-2-ones were prepared in excellent enantioselectivities (up to 99% ee) via an organo-catalyzed cascade procedure with N-TFA-Gly-Bt and α,β-unsaturated aldehydes as the substrates. The corresponding tetrahydro-2H-pyran-2-ones can be used for further synthetic transformations that furnish chiral-substituted 3-aminopiperidin-2-ones with high levels of stereoselectivity.
Journal of Organic Chemistry published new progress about Diastereoselective synthesis. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, COA of Formula: C9H7BrO.
