The present invention relates to a compound represented by the formula wherein each symbol is as defined in the present specification, which has a superior RBP4-lowering action and is useful as a pharmaceutical composition for the prophylaxis or treatment of a disease or condition mediated by an increase in RBP4.
The present invention provides a process for producing (R)-styrene oxides represented by the formula (1):
wherein R1, R2, R3 and X are as defined in the specification, which comprises treating a mixture of (R)- and (S)-phenylhalogenomethylcarbinols with a lipase in the presence of a carboxylate to preferentially convert the (S)-phenylhalogenomethylcarbinols,
and treating a mixture of the formed carbinol alkylates (3) and (R)-phenylhalogenomethylcarbinols with a base to cyclize the (R)-phenylhalogenomethylcarbinols, and also provides an industrially excellent process for producing (R)-styrene oxides (1) which comprises using a mixture enriched with (R)-phenylhalogenomethylcarbinols as the mixture of (R)- and (S)-phenylhalogenomethylcarbinols (2).
本发明提供了一种生产由式(1)表示的(R)-苯乙烯氧化物的工艺:
其中 R1、R2、R3 和 X 如说明书中所定义,该工艺包括在有羧酸盐存在的情况下,用脂肪酶处理(R)-和(S)-苯基卤代甲基甲醇的混合物,以优先转化(S)-苯基卤代甲基甲醇、
还提供了一种生产(R)-苯乙烯氧化物(1)的工业化优良工艺,该工艺包括使用富含(R)-苯基卤代甲基甲醇的混合物作为(R)-和(S)-苯基卤代甲基甲醇的混合物(2)。

novel N-aryl tetracyclicdicarboximide MM0299 (1) with robust activity against gliomastem-likecells that potently and selectively inhibits lanosterol synthase leading to the accumulation of the toxic shunt metabolite 24(S),25-epoxycholesterol. Herein, we delineate a systematic and comprehensive SAR study that explores the structural space surrounding the N-aryl tetracyclicdicarboximide scaffold. A
