Croton ates

Chiral fl-amino esters. The conjugate addition of primary amines to alkyl crotonates proceeds in satisfactory yield when carried out under high pressure. French chemists have recently examined this reaction using crotonates derived from chiral alcohols. Thus addition of diphenylmethylamine to 8-phenylmenthyl croton-ate proceeds in 85-90% chemical yield and in 60% de. Optical yields are increased... 

Perbenzoic acid is an important reagent for the preparation of epoxides from olefinic compounds (method 126). When the epoxides are unstable in aqueous solution, glycols ate formed directly. The over-all reaction results in trans addition of hydrcscy groups to the double bond for crotonic and isocrotonic acids. ... 

Mixtures of isomers are also formed in the reactions of methyl ( )-crotonate and diethyl fumar-ate with (l-methylethylidene)cyclopropane (1).
