4-methoxyphenyl methy

A concerted unimolecular mechanism has been proposed to account for the formation of elimination products on solvolysis of the tertiary l-(4-methoxyphenyl)-3-methy 1-3-butyl derivatives (38-X) in aqueous solvents.19 Thus, in 50 50 (v/v) CF3CH20H-H20, (38a) and (38b) give 39% and 56%, respectively, of the alkene... 

Treatment of the /3-lactam, 3,3-dimethoxy-l-p-methoxyphenyl-4-p-methoxyphenyliminomethyl-2-azetidinone (3, R = H), with stannous chloride in dichloromethane for 20 h gave 1,4-bisf/ -methoxyphenyl)-2,3(l//,4//)-pyrazine-dione (5, R = H) in 95% yield by ring expansion via the acetal (4) 874 the 4-methy-lated substrate (3, R = Me) likewise gave 1,4-bisf p-methoxyphenyl)-5,6-dimcthyl-2,3(lH,4tf)-pyrazinedione (5, R = Me) (99%).874 cf-1740... 

Methyl 2-(4-methoxyphenyl)-6-methy]-l,4,3-oxathiazine-5-carbox3flate (7) has been synthesized as the so far only example of this ring system.51 Treatment of 5-(4-mcthoxyphenyl)-l,3.4-oxathiazol-2-one (4) with methyl diazoacetoacetate in the presence of rhodium(II) acetate in refluxing benzene yields 4-methoxybenzonitrile (64%), 1,3-dithietanes (8, 25%), thiiranes (9, 5% cis/trans mixtures), and 6% of a compound C13H,3N04S, which was identified as 7 by X-ray analysis. 

To an ice-cooled solution of 2.41 g A-(2-methy 1-5-methoxyphenyl) benzamide (10 mmol) in 20 mL dry THF was added 13.75 mL 1.6 M n-butyllithium in hexane (22 mmol) dropwise under a nitrogen atmosphere. This mixture was stirred at room temperature for...
