To confirm the absolute stereoselectivity of the reaction introducing 2H at 13C on the β face, 13β 2H I was transformed into four deuterated derivatives of I and sparteine, the structures of which have previously been determined (in two cases by X-ray analysis). Angustifoline (I), ...
It is commonly used as a building block in the synthesis of peptides and peptidomimetics, offering a versatile platform for the modification and stabilization of peptide structures. N-Benzyloxycarbonyl-D-proline is also utilized in the development of pharmaceuticals targeting various diseases, including...
Undergraduate organic chemistry students,as they study conformationalanalysis and stereochemistry, frequently have trouble manipulatingthree-dimensional structures on a two-dimensional page or screen.The inability to accurately convert three-dimensional bond-line representationsinto Fischer projections is one exampl...

Proline is a well-documented osmolyte and signaling molecule which accumulates rapidly in growing plants under abiotic stresses and contributes to stabilizing membrane structures, enzymes, proteins synthesis, as well as regulating cytosolic acidity (Hayat et al., 2012; Wu et al., 2022). The prolin...
Our structure of the in-line aligned env22 twister ribozyme is compared with two recently reported twister ribozymes structures, which adopt similar global folds, but differ in conformational features around the cleavage site. 1 Structural Biology Program, Memorial Sloan-Kettering Cancer Center, New ...
structure (Figure 2A). CD studies in sodium solution were also carried out to examine the effects of compounds on different G-quadruplex structures, although they were lessphysiologically relevant. However, upon addition of 2b to HTG21 in buffer ...
