Are there alternatives to 1-({[(2-Methyl-2-propanyl)oxy]carbonyl}amino)cyclopropanecarboxylic acid (CAS: 144243-24-3) in synthesis?

Several alternatives can be used in the synthesis of 1-({[(2-Methyl-2-propanyl)oxy]carbonyl}amino)cyclopropanecarboxylic acid (CAS: 144243-24-3), including 1-({[(2-Methyl-2-ethoxy)carbonyl]amino}cyclopropanecarboxylic acid and 1-({[(2-Methyl-1-methoxyethyl)oxy]carbonyl}amino)cyclopropanecarboxylic acid. These analogs can be synthesized using similar synthetic routes, but with different functional groups. Common alternative reagents include carboxylic acid derivatives, such as acid chlorides and anhydrides, which can provide similar functionality without the need for the specific methyl-substituted alkyl group.
