Diphenyloxazinone glycinate chiral templates enable asymmetric synthesis of complex natural products like cylindrospermospin and spirotryprostatins. These templates also show promise for synthesizing alkaloids such as quinine.
Area of Science:
- Organic Chemistry
- Synthetic Chemistry
- Natural Product Synthesis
Background:
- Chiral templates are crucial for controlling stereochemistry in asymmetric synthesis.
- Developing efficient methods for synthesizing complex natural products remains a key challenge in organic chemistry.
Purpose of the Study:
- To demonstrate the utility of diphenyloxazinone glycinate chiral templates in asymmetric synthesis.
- To synthesize cylindrospermospin, 7-epi-cylindrospermopsin, 7-deoxycylindrospermopsin, spirotryprostatins A and B, and explore their application towards quinine, nakadomarin A, and palau'amine.
Main Methods:
- Application of diphenyloxazinone glycinate chiral auxiliaries.
- Asymmetric synthesis methodologies.
- Total synthesis of natural products.
Main Results:
- Successful asymmetric synthesis of cylindrospermospin, 7-epi-cylindrospermopsin, 7-deoxycylindrospermopsin, and spirotryprostatins A and B.
- Demonstrated applicability of the chiral templates in synthetic studies towards quinine, nakadomarin A, and palau'amine.
Conclusions:
- Diphenyloxazinone glycinate chiral templates are effective tools for the asymmetric synthesis of diverse and complex natural products.

Preparation of 1° Amines: Gabriel Synthesis
Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
