New and efficient procedures for the synthesis of stereodefined 2-(hetero) aryl and 2-methyl substituted alkyl 2-alkenoates having very high stereoisomeric purity
Rossi, Renzo
, p. 4495 - 4498 (1992)
Stereodefined 2-(hetero)aryl and 2-methyl substituted alkyl 2-alkenoates of general formulai and2 have been synthesized with a high degree of stereoselectivity as well as in good overall yields starting from alkyl 2-alkynoates,4.
Trisubstituted Olefins via Ester-Derived (Silyloxy)acetylenes: A Highly Stereoselective Alternative to the Horner-Wadsworth-Emmons Reaction
Kowalski, Conrad J.,Sakdarat, Santi
, p. 1977 - 1979 (2007/10/02)
Crude ((triisopropylsilyl)oxy)acetylenes 2, prepared in one step from common esters 1, react with aldehydes in 60-65 percent overall yield after methanol quench to afford α,β-unsaturated esters 3 with very high E/Z stereoselectivity.
