A general, efficient, and highly diastereoselective method for the synthesis of structurally and sterically diverse P-chiral phosphine oxides was developed. The method relies on sequential nucleophilic substitution on the versatile chiral phosphinyl transfer agent 1,3,2-benzoxazaphosphinine-2-oxide, which features enhanced and differentiated P–N …Since stem cells emerged as a new generation of medicine, there are increasing efforts to deliver stem cells to a target tissue via intravascular injection. However, the therapeutic stem cells lack the capacity to detect and adhere to the target tissue. Therefore, this study presents synthesis of a bioactive hyperbranched polyglycerol (HPG) that can noninvasively associate with stem …The procedure carried out followed the given information in: CHE 135 Experiment 3, General Chemistry III Lab, Spring Quarter 2019-2020, DePaul University.

Redox enzymes play a central role in generating structural complexity during natural product biosynthesis. In the postassembly tailoring steps, redox cascades can transform nascent chemical scaffolds into structurally complex final products. Chaetoglobosin A (1) is biosynthesized by a hybrid polyketide synthase–nonribosomal peptide synthetase. It belongs …

My school has CHEM135 (which transfers to UMD) that is notoriously difficult because people taking the course are skipping the CHEM 131 + CHEM 132 route (both taken in different semesters). Most people are failing CHEM135 at my school and it is even to the point that they are thinking of not offering the course next semester.

This course replaces both CHEM 131A and 132A. Semester Hours: 4 : Prerequisites: CHEM 003A. Students registering for this course should also register for the corresponding laboratory course CHEM 137. Credit given for either 131A and 132A or 135. May not be taken on a Pass/D+/D/Fail basis.
