The results of π−–emulsion interactions are compared with those of p–emulsion interactions. The dependence of the parameterRAon mass numberAhas been examined and compared with the existing models of hadron–nucleus interactions.doi:10.1139/P79-231A. Mozumder...
The asymmetric synthesis of two naturally occurring 5-hydroxy-γ-butyrolactones, (4R,5R)-5-hydroxy-4-decanolide (1a) and (−)-muricatacin (2), is described using a general alkyne-mediated strategy. The key steps involved are Sonogashira coupling for the desired carbon-chain extension ...
