An Intramolecular Version of the Claisen Ester Condensation. Make sure you can draw the product for the hydrolysis of a cyclic amide lactam since reactions of cyclic molecules and their reverse intramolecular reactions are common fodder for exams.

Solved Draw The Product Of The Below Intramolecular Claisen Chegg Com

This reaction comes up later in the Strecker synthesis of amino acids which begins with the addition of cyanide ion to an imine followed by hydrolysis of the nitrile to give.

. 12-addition reactions are all of those where the nucleophile attacks the carbonyl groupFor example the reaction of carbonyl compounds with. Note that were still forming a C-C π bond and breaking two single bonds to carbon but in this case our base is methanol hence the formation of the salt CH3OH2 Cl-. So the Michael reaction is a particular type of conjugate addition reaction that ɑ β-unsaturated carbonyl compounds undergo with nucleophiles.

However if we take a molecule like ethyl chloride and treat it with methanol. Like in the first reaction below. Reactions in which a larger molecule is formed from smaller components with the elimination of a very small by-product such as water are termed Condensations.

Reaction 5 is an interesting example of an intramolecular aldol reaction. Its still an elimination reaction but in this instance were merely added methanol CH3OH. Hence the following examples are properly referred to as aldol condensations.

When a difunctional ester is used if the ester groups are positioned so that there are 4 or 5 carbon atoms between them an intramolecular version of the Claisen condensation can occur and is especially useful in the construction of five and six-membered rings. Such reactions create a new ring. In general ɑ β-unsaturated carbonyl compounds can undergo a 12- or 14-addition reaction.
