Simple and New Protocol for the Synthesis of Novel (z)-3-Arylidenebenzothiazepin-4-ones Using Baylis–Hillman Derivatives
摘要:
A simple synthesis of novel (Z)-3-arylidene-2,3- dihydrobenzo[b][1,4]thiazepin-4(5H)-ones from bromo compounds derived from Baylis-Hillman adducts involving selective S-alkylation followed by a lactum formation has been described.
