This article will discuss the synthetic routes of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid, which can be broadly classified into two categories: chemical synthesis and biological synthesis.

Chemical Synthesis

Chemical synthesis is the process of producing a desired chemical compound using chemical reactions.
There are several chemical synthesis routes for the synthesis of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid, which can be broadly classified into three categories: direct chemical synthesis, indirect chemical synthesis, and semisynthetic synthesis.

1. Direct Chemical Synthesis

Direct chemical synthesis is the process of synthesizing a desired compound directly from its starting materials without any intermediate steps.
One of the most common direct chemical synthesis routes for the synthesis of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid is the Harsch-Schifflotti reaction.
In this reaction, benzaldehyde and para-formylphenylglycine are reacted in the presence of a Lewis acid catalyst, such as aluminum chloride, to produce (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid.

2. Indirect Chemical Synthesis

Indirect chemical synthesis is the process of synthesizing a desired compound through one or more intermediate steps.
One of the most common indirect chemical synthesis routes for the synthesis of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid is the Paal-Knorr synthesis.
In this reaction, a substituted benzaldehyde is reacted with a substituted glycine in the presence of a strong acid catalyst, such as hydrochloric acid, to produce a substituted β-alanine.
This β-alanine is then transformed into (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid through a series of chemical reactions, such as hydrolysis, N-acylation, and electrophilic substitution.

3. Semisynthetic Synthesis

Semisynthetic synthesis is the process of synthesizing a desired compound using a combination of chemical and biological processes.
One of the most common semisynthetic synthesis routes for the synthesis of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid is the Strecker synthesis.
In this reaction, a substituted benzaldehyde and a substituted amino acid are reacted in the presence of a strong acid catalyst, such as hydrochloric acid, to produce a substituted β-alanine.
This β-alanine is then transformed into (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid through a series of chemical reactions, such as hydrolysis, N-acylation, and electrophilic substitution.

Biological Synthesis

Biological synthesis is the process of producing a desired chemical compound using biological systems, such as microorganisms or enzymes.
There are several biological synthesis routes for the synthesis of (S)-1-(benzyloxycarbonyl)hexahydropyridazine-3-carboxylic acid, which can be broadly classified into two
