While the prop-2-ynyl acetates (1) rearrange to the allenyl acetates (2) in boiling benzene containing copper(I) chloride, in the presence of silver trifluoroacetate the butadienyl acetates (3), useful in Diels–Alder reactions, are formed in high yield.
Michaeladdition reaction of α-branched aldehydes to β-nitroacrylates was successfully carried out by using a mixed catalyst consisting of a primary amino acid, L-phenylalanine, and its lithium salt to give β-formyl-β′-nitroesters having a quaternary carbon centre in good yields (up to 85%) with high enantioselectivity (up to 98% ee). By using benzyl β-nitroacrylates as Michael acceptors, the obtained

three‐component reaction of aryldiazoacetates, aromatic amines, and β‐nitroacrylates was achieved to obtain γ‐nitro‐α‐amino‐succinates in good yields and with high diastereo‐ and enantioselectivity. This reaction is proposed to proceed through the enantioselective trapping of RhI‐associated ammoniumylides by nitroacrylates. This new transformation represents the first example of RhI‐carbene‐induced ylide transformation
