a)
Interpretation:
The products formed in the reaction given are to be identified. The mechanism of the reaction also is to be provided.
Concept introduction:
The protonation of the imine yields a iminium ion. The nucleophilc attack by water followed by exchange of proton from O to N and elimination of a proton will yield an
To identify:
The products formed in the reaction given and to provide the mechanism of the reaction.
b)
Interpretation:
The products formed in the reaction given are to be identified. The mechanism of the reaction also is to be provided.
Concept introduction:
The protonation of the imine yields a iminium ion. The nucleophilc attack by water followed by exchange of proton from O to N and elimination of a proton will yield an amine and an aldehyde or ketone as the product.

- Predict the product(s) and provide the mechanism for each reaction below.arrow_forwardPredict the product(s) and provide a mechanism:arrow_forwardA step in a synthesis of PGE1 (prostaglandin E1, alprostadil) is the reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Propose a mechanism for formation of this bromolactone and account for the observed stereochemistry of each substituent on the cyclohexane ring. Alprostadil is used as a temporary therapy for infants born with congenital heart defects that restrict pulmonary blood flow. It brings about dilation of the ductus arteriosus, which in turn increases blood flow in the lungs and blood oxygenation.arrow_forward
- Predict the product(s) and provide the mechanism. d Br forarrow_forwardPredict the product(s) and propose a mechanism for the following reaction. LOH H₂SO4 Heatarrow_forwardPredict the product(s) for each elimination reaction below. In each case show the mechanism. What do the mechanisms have in common? Why?
