AI Technical Summary
In the existing Alibring synthesis, the synthesis of key intermediate fragment VI has problems such as high cost, complex operation and low selectivity, making it difficult to achieve large-scale industrial production.
A new synthesis method of intermediate fragment VI is provided. Starting from L-arabinose through 14-step reaction, the combination of inert gas protection, a combination of multiple organic solvents and specific protective groups is achieved, and synthesis with ease of operation and high yield is achieved.
This method simplifies the synthesis steps, improves the reaction yield, reduces the synthesis cost, is suitable for industrial large-scale production, and provides a synthesis route for the new Elibrin intermediate ERB.
