Expedient Baylis–Hillman reaction protocol to functionalize cyclohexa-2,4-dienones

Several masked o-benzoquinone (MOB; 6,6-dimethoxy-cyclohexa-2,4-dienone derivatives) derivatives successfully took part in the Baylis–Hillman (BH) reaction with various aldehydes and ketones to furnish the corresponding condensation products. To our knowledge, cyclohexa-2,4-dienone systems in this study are utilized for the first time in the BH reaction.
