Strain-Release Driven Annulations of Bicyclo[1.1.0]butanes and Ring-Opening of Donor-Acceptor Cyclopropanes
The concept of strain release has long captivated chemists, particularly in the context of highly strained molecular frameworks such as bicyclo[1.1.0]butanes (BCBs), which possess a remarkable strain energy of 63.9 kcal/mol. ... -
Biotransformation of terpenoids in rats : studies on the pulmonary mixed function oxidase systems
Metabolic fate of natural products in mammals has been of interest since the beginning of this century. Terpenoids, one of the largest groups of naturally occurring compounds, are components of many commonly used food ... -
Metabolism of L Phenylalanine and Tyrosine
Rhizoctonia solani employs two pathways, viz., phenylpyruvate pathway and cinnamate pathway, to degrade L-phenylalanine. The intermediates in the phenylpyruvate pathway are phenylacetate, o-hydroxyphenylacetate, and ... -
