One of the organocatalysts 1, 4-diazabicyclo [2.2. 2] octane (DABCO) is an excellent solid
catalyst in a number of reactions. It is also a good nucleophile and a base in numerous …

DABCO (1, 4-diazabicyclo [2.2. 2] octane) has garnered a lot of interest for numerous
organic transformations since it is a low-cost, environmentally friendly, highly reactive …

The Michael reaction, a cornerstone in organic chemistry, continues to revolutionize the field
with its unparalleled versatility in forming carbon–carbon, carbon–oxygen, carbon–nitrogen …

The conjugate addition of amines to conjugated alkenes (commonly known as aza-Michael
reaction) constitutes a key step for the synthesis of various complex natural products …

MgO nanoparticles were prepared by an improved sol–gel technique which appeared to
have narrow size distributions. The synthesized magnesium oxide nanoparticles were used …

An unexpected reaction between 4-phenylurazole and fumaric esters which led to the
formation of 5-alkylidene derivatives of hydantoin is described in this paper. The reaction …

Asymmetric Michael addition of β-keto esters with trans-β-nitroolefins using chiral amino
