Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 604-69-3, Name is beta-D-Glucose pentaacetate, molecular formula is , belongs to dioxoles compound.

A new approach to alkaloid-like systems: synthesis and crystal structure of 1-(2-acetyl-11-methoxy-5,6-dihydro[1,3]dioxolo[4,5-g]pyrrolo[2,1-a]isoquinolin-1-yl)propan-2-one
The title compound, C19H19NO5, (I), is the product of a domino reaction between cotarnine chloride and acetylacetylene catalysed by copper(I) iodide. The molecule of (I) comprises a fused tetracyclic system containing two terminal five-membered rings (pyrrole and 1,3-dioxole) and two central six-membered rings (dihydropyridine and benzene). The five-membered 1,3-dioxole ring has an envelope conformation and the central six-membered dihydropyridine ring adopts a twist-boat conformation. The acyl substituent is almost coplanar with the pyrrole ring, whereas the methoxy substituent is twisted by 27.93 (16)degrees relative to the benzene ring. The 2-oxopropan-1-yl substituent is roughly perpendicular to the pyrrole ring. In the crystal, molecules are stacked along the a-axis direction; the stacks are linked by weak C-H center dot center dot center dot O hydrogen bonds into puckered layers lying parallel to (001).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 604-69-3, in my other articles. SDS of cas: 604-69-3.
