H. Fuwa
[Full Text PDF(J-STAGE)]
Free Access Article
 | Total synthesis of structurally complex marine oxacyclic natural products, (−)-gambierol, (−)-brevenal, and (+)-neopeltolide, has been accomplished by exploiting Suzuki–Miyaura coupling of enol phosphates, which paved the way for biological investigations on these scarcely available marine secondary metabolites. |

[Full Text PDF(J-STAGE)]
[Supporting Information]
Free Access Article
The electrochemical behavior of a covalently functionalized hyperbranched polymer with a vitamin B12 derivative (B12–HBP) was investigated by cyclic voltammetry and UV–vis spectroscopy. The B12–HBP showed excellent properties as a homogeneous catalyst for the electrochemical degradation of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT).
