Intramolecular Diels-Alder Reaction of Furans with Allenyl Ethers Followed by Phenylthio and Trialkylsilyl Groups Rearrangement
摘要:
AbstractA new reaction involving an intramolecular Diels‐Alder reaction of a furan diene with an allenyl ether dienophile followed by phenylthio group rearrangement was discovered. Treatment of the propargyl ethers 2a‐c with t‐BuOK in t‐BuOH at 85 ° C gave the phenylthio group rearrangement products 5a‐c and 6a‐c. A reaction involving an intramolecular Diels‐Alder reaction of a furan diene with an allenyl ether dienophile followed by trialkylsilyl group rearrangement is also demonstrated.
