Direct transformation of Baylis Hillman adducts into molecules of interest is a crucial process, thereby allylic hydroxy protected or halogenated BH adducts are commonly preferred. Herein, we report a azidophosphonium salt catalysed (QPS) straight forward protcol for synthesising structurally demanding (E) / (Z) cinnamyl-1H-1,2,3-triazoles and halomethyl coumarins from unaltered BH adducts. Novel methodology, efficient catalyst and direct utilization of BH adducts in presence mild reaction conditions identifies the reported procedures as a powerful synthetic tool.
