Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

Tetrahydroisowuinolin derivatives and phthalide derivatives were designed and synthesized on the basis of a PDE4 inhibitor pharmacophore model set up through computer simulation. Some tetrahydroisowuinolin derivatives synthesized were evaluated on their activity against PDE4 for study on the structure-activity relationship.(7-cyclopentyloxy)-6-methoxy-3,4-dihydroisoquinolin-2(1H)-yl(4-hydroxy-3-methoxyphenyl)methanone (155) and Methyl 7--6-methoxy-2-(4-methoxy- benzoyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylate (170) showed good activity against PDE4, which were chosen as the lead compounds to design and synthesize another analogs in order to develop selective PDE4 inhibitors with better activity.

Benzoyl chloride was treated with potassium selenocyanate in dichioromethane by using polyethylene glycal-400 as the solid-liquid phase transfer catalyst to yield the corresponding benzoyl isoselenocyanate. This intermediate did not need to be isolated and directly reacted with arylamines, affording the N-benzoyl-N'-arylselenoureas 2a~2p. These compounds were characterized by IR, 1H NMR spectra and elemental analysis and the single crystal structure of 2k has been confirmed by X-ray crystallographic analysis.
