31, Methods: Simvastatin was synthesized from lovastatin via several steps involving acetylization, methylation , hydrolytic decomposition and cyclization reactions.

32, Using BF3-Et2O as a catalyst, the title compound was synthesized from allyl alcohol and epichlorohydrin by a series reaction included addition and cyclization .

33, METHODS Bropirimine was synthesized by 3 steps reaction of acylation, cyclization and bromination with ethyl acetoacetate as staring material.

34, Cyclization and tautomerization give intermediate 10 , which will react with a third equivalent of the grignard reagent ( 2 ) to give a dimagnesium indole salt ( 12 ).

35, Celecoxib as a cyclooxygenase-2 inhibitor, was synthesized from p-methylacetophenone and ethyl trifluoroacetate by successively condensation and cyclization in 67% overall yield.

36, The cyclization reactions of carbodiimide 14 with chiral amide ethyl ester was firstly studied. The results showed that the carbodiimide 14 reacted quickly with amide ethyl ester at room temperature.

37, Tinoridine hydrochloride was synthesized from benzylamine by condensation, cyclization, decarboxylation,[www.Sentencedict.com] cyclization and then salt formation in an overall yield of 55.2%.

38, Methods: Simvastatin was synthesized from lovastatin via acetylization, methylation, hydrolytic decomposition and cyclization reactions.

39, In Chapter III, we have developed the Ag-catalyzed intramolecular organic azide and alkyne cyclization to synthesize of 1,3-disubstituted isoquinolines or non-substituted isoquinolines.

40, That is dehydrogenation and cyclization of paraffins, dehydrogenation and aromatization of naphthenes, and cracking reaction to form C 5 lighter products.
