The benzyl can be selectively removed by visible light or near visible light. Method for protecting allyl and propargyl group
-
Paragraph 0028, (2021/10/16)
The invention provides a method for selectively removing benzyl, allyl and propargyl protecting groups by visible light or near visible light, namely a substrate containing benzyl, allyl or propargyl protecting groups. The method has the advantages of simple operation, safe and clean visible light or near visible light as excitation conditions, cheap and easily available reagents, high reaction yield, high reaction chemistry and regional selectivity, and is suitable for selective removal of benzyl, allyl and propargyl protecting groups in various substrates.

The invention discloses a method for preparing beta-phenethyl alcohol. According to the method, acetic acid-3-butene-1-alcohol ester and 1,3-butadiene are adopted as raw materials, and the preparation of beta-phenethyl is finished by adopting Diels-Alder, hydrolysis and dehydrogenation reactions. lewis acid supported by fullerol as a carrier is adopted as the catalyst for the Diels-Alder reaction, the atom utilization rate is high, the total yield can reach 87%-95%, the purity of products can reach 99.92wt%-99.98wt%, and an oxidation reaction process and a high-pressure hydrotreatment reaction process are not adopted, so that the production process is safe and environmentally friendly.

(Chemical Equation Presented) 1,5-Cyclooctadiene was deprotonated under LICKOR conditions and reacted with Merrifield resin to afford an immobilized cyclooctadiene in high yield. This polymer is effective as a halogen scavenger, while hydroboration leads to a supported 9-BBN analogue. The latter exhibits similar regioselectivity to 9-BBN in olefin hydroboration.
