Photochemical Rearrangement of 8- methyl Spiro [2.5] oct-7-en-4-one to 4-methyl Spiro [2.5] oct-4-en-6-one
Irradiation of &methyl spiro [2.5] oct-7-en-4-one through its singlet excited state resulted in the formation of 4-methyl spirO [2.5] oct-4-en -6-one. We have used the cyclopropyl moiety in the molecule as a probe to study the operating mechanism in the photochemistry of ?, ?-unsaturated compounds. The results showed that this photoisomerization probably occurs through a concerted process.

In the title thio-ether dihydrate, C(18)H(10)Cl(2)N(2)S·2H(2)O, the S-bound quinolinyl residues are almost orthogonal, forming a dihedral angle of 72.36 (4)°. In the crystal, the four water mol-ecules are connected via an eight-membered {⋯OH}(4) synthon with each of the four pendent water H atoms hydrogen bonded to a pyridine N atom to stabilize a three-dimensional architecture.

Aim: To assess whether intensity modulated radiotherapy (IMRT) offers any advantages compared to three-dimensional conformal radiotherapy (3DCRT) when treating the ilio-inguinal lymph-node basin after therapeutic lymphadenectomy for melanoma. Method: 15 consecutive patients receiving adjuvant radiotherapy (48 Gy in 20 fractions) were selected for the study. Simulation, volume generation and goa...
