Simple, One-Pot, and Facile Synthesis of Angularly Fused [6-7-5], [6-7-6], [6-7-7], and [6,7] Ring Systems Using Baylis-Hillman Acetates

The Baylis–Hillman reaction: a new continent in organic chemistry – our philosophy, vision and over three decades of research

This mini review describes in brief the way in which our research has contributed towards the development of the Baylis–Hillman reaction as a powerful tool in synthetic chemistry, offering unending opportunities and intellectual challenges to understand and address the present day requirements in the area of organic chemistry.

Efficient Synthesis of Pyrazole Fused [6-7-5] Tricyclic Frameworks via Intramolecular Friedel–Crafts Reaction of Morita–Baylis–Hillman Adducts

A novel and efficient synthesis of pyrazole fused[6-7-5]tricyclic derivatives via AlCl3-catalysed intramolecular Friedel–Crafts reaction of the Morita–Baylis–Hillman adducts was described and a plausible mechanism was given.

Highly chemoselective Baylis-Hillman and aldol reactions of 2H-thiopyran-4(3H)-one using tertiary amine catalysts in aqueous media

For the first time, the Baylis-Hillman (BH) reaction of 2H-thiopyran-4(3H)-one is investigated, and surprisingly, the reaction of 2H-thiopyran-4(3H)-one with aldehydes in the presence of different tertiary amines shows excellent chemo- and regioselectivity in water. At room temperature, DBU affords BH adducts, but with DABCO, aldol products were obtained. In the case of DABCO, Et(3)N, or DMAP, domino aldol-rearrangement reactions occurred at 45-50 °C.
