, p. 1711 - 1720 (2007/10/02)
Chiral butenolides react with butandiene at 210 deg C giving optically active bicyclic compounds wiht excellent diastereoselectivity, in good yields.Optical purity of the adducts has been verified either by chemical correlation and/or by the use of Eu(hfc
CHIRAL BUTENOLIDES AS DIENOPHILES IN DIELS-ALDER CYCLOADDITIONS
Ortunno, R. M.,Corbera, J.,Font, J.
, p. 1081 - 1084 (2007/10/02)
Differently substituted chiral butenolides, prepared from D-ribonolactone, react with butadiene at 210 deg C affording enantiomerically pure bicycloadducts as single diastereoisomers, in good yields.The ability of protoanemonin (formed in some pyrolytic r
