A general synthesis of dibenzoxepine lactams has been developed using a one-pot Cu-catalyzed etherification/aldol condensation cascade reaction. The reaction of 4-hydroxyisoindolin-1-one with a wide range of 2-bromobenzaldehydes in the presence of a copper catalyst provided various aristoyagonine derivatives in good yields.
Expeditious synthesis of benzopyrans via lewis acid-catalyzed C-H functionalization: Remarkable enhancement of reactivity by an ortho substituent

supporting information; experimental part, p. 1732 - 1735 (2010/09/05)
An expeditious construction of a benzopyran skeleton via Lewis acid-catalyzed C-H functionalization was achieved. In this process, a [1,5] hydride shift and 6-endo cyclization successively occurred to give benzopyrans. The presence of substituents ortho to the alkoxy group significantly enhanced the reactivity, affording the desired compounds in excellent chemical yields with short reaction times.

A cyclohexane derivative having the function of reducing a blood sugar level and having preferable properties required of medicines, such as long-lasting drug activity, metabolic stability, and safety; and a medicinal composition for use in the prevention or treatment of diseases attributable to hyperglycemia, such as diabetes, e.g., insulin dependent diabetes mellitus (type 1 diabetes) or noninsulin-dependent diabetes mellitus (type 2 diabetes), complications of diabetes, and obesity. The derivative is a compound represented by the formula (I): (wherein A is -O-, -CH2-, or -NH-; n is an integer selected between 0 and 1; R6 and R7 each independently is hydrogen or C1-6 alkyl; m is an integer selected among 1-3; Q is selected among the following formulae Q1 to Q5; Ar1 is optionally substituted arylene or optionally substituted heteroarylene, provided that the heteroarylene may be bonded to an aromatic carbocycle or aromatic heterocycle to form a fused ring; and Ar2 is optionally substituted aryl or optionally substituted heteroaryl), a prodrug of the compound, or a pharmaceutically acceptable salt of either. Also provided are a medicine, a medicinal composition, or the like each containing the compound.

PCT No. PCT/JP96/03650 Sec. 371 Date Jun. 19, 1998 Sec. 102(e) Date Jun. 19, 1998 PCT Filed Dec. 13, 1996 PCT Pub. No. WO97/22574 PCT Pub. Date Jun. 26, 1997An improved process for producing a catechol derivative (1) useful as a intermediate of pharmaceuticals and agricultural chemicals, being shown by the following reaction scheme. The process is characterized in that formulation in the first step is carried out in the two stages, that is, the reaction is carried out in the presence of a tin catalyst at 60-85 DEG C. to a conversion of 30 to 80% and then is completed at 95-105 DEG C. to produce a salicylaldehyde derivative (3) in a high yield and a high selectivity. Thereby, the objective catechol derivative (1) can be obtained in a high yield and with a high purity. In the above formula, R is alkyl, cycloalkyl, aralkyl, alkoxy, halogen atom, allyl, or aryl, and R1 is a hydroxy protective group.
