Homework problem 4.24 “Altogether, the free radical chlorination of (S)-(-)-1-chloro-2-methylbutane gave six fractions of formula C5H10Cl2. Four fractions were found to be optically active, and two fractions optically inactive. Draw structural formulas for the compounds making up each fraction....
Elegant asymmetric synthesis of hasubanan alkaloids have been developed over the past decades. However, a divergent approach leading to all three sub-classes of this family of natural products remains unknown. We report herein the realization of such an
All of these techniques are quite powerful for obtaining structural information when com- bined with optimization algorithms and density functional theory (DFT) calculations. So far, the dif- ferent types of algorithms have been developed to search the low-energy structure on the complicated potential...

classified by Pilli19,20into eight structural groups (see Supplementary Fig.1). The attractive bioactivities15,16and unique polycyclic structures of these alkaloids have led to intense phytochemical, synthetic, and biomedical investigations, and many innovative total syntheses have been achieved16,18,19...
Covalent organic frameworks, cross-linked crystalline polymers constructed from rigid organic precursors connected by covalent interactions, have emerged as a promising class of nanoporous materials owing to their highly desirable combination of attributes, including facile chemical tunability, structural diversit...
