A novel transacylation method for the synthesis of α-N-acyl-β-lactones; application to (±)-diacetylobafluorin and (+)-SQ 26,517
Abstract
Stereoselective synthesis of (±)-diacetylobafluorin and (+)-SQ 26,517 has been accomplished via transacylation of α-N-(2-nitrophenyl)sulphenyl-β-lactones with 2-acylmercaptobenzothiazoles.
