Rhodococcus erythropolis SET1, a novel nitrilehydrolysing bacterial isolate, has been undertaken with 34 nitriles, 33 chiral and 1 prochiral. These substrates consist primarily of β-hydroxy nitriles with varying alkyl and aryl groups at the β position and containing in several compounds different substituents α to the nitrile. In the case of β-hydroxy nitriles without substitution at the α position
method for the preparation of allyl chlorides from Baylis–Hillmanadducts has been developed using triphosgene/pyridine system. This method is best illustrated by its advantages like operational simplicity, excellent yields, short reaction time, simple procedure and stereoselectivity. The preparation of allyl chlorides from Baylis-Hillmanadducts has been described using triphosgene & pyridine system
A series of pyran derivatives (5–27) were synthesized in good yields by utilizing Baylis–Hillman chemistry and were further investigated for their in vitro anticancer, antibacterial, and antifungal activities. Most of the tested compounds exhibited promising antibacterial activity as compared to the standard towards Gram-positive bacterial strains. The compounds 5–7, 11–13, and 17–19 displayed two-fold

has been developed by the C–H functionalization of anilides with Morita–Baylis–Hillman (MBH) bromides in the presence of copper chloride, TBHP and acetic acid. Unsubstituted as well as ortho/meta-substituted anilides exclusively give rise to the para-allylated products, whereas para-substitution brings about the formation of ortho-allylated anilides.
