Experimental and theoretical studies of (4 + 1) annulations between α‐oxoketenes and stable phosphorous, nitrogen, or sulfur ylides

Abstract

α Oxoketenes generated in situ by a microwave assisted Wolff rearrangement-at 170°C were found to react with stabilized sulfur ylides in (4 + 1) annulation processesto afford functionalized 3 hydroxyfurans.-Theoretical mechanistic investigations revealed that the reaction proceeds in two steps via a short-lived betaine intermediate, a general feature of the reactions of α oxoketenes-with stable phosphorous, nitrogen, and sulfur ylides.
