diverse MBH adducts was prepared via the reaction of derivatives of 2‐chloroquinoline‐3‐carbaldehyde and various activated alkenes in good yields. Many of these compounds were found to be potent when tested against human prostate cancer (Pc‐3) cell line in vitro. Among all the compounds tested N‐(2‐chloro‐3‐(2‐cyano‐1‐hydroxyallyl)‐7‐phenoxyquinolin‐6‐yl)formamide (IC50 = 1.2 μg mL−1) was identified as

phosphorus-free catalyst for the Morita–Baylis–Hillmanreaction is disclosed. A bicyclicimidazolylalcohol having a Lewis basic center associated with a hydrogen-bond donor group was used as catalyst for the reaction. Aliphatic cycloalkanones such as 2-cyclopentenone and 2-cyclohexanone and aliphatic and aromatic aldehydes were used successfully, and the reaction was found to work nicely using water
