〖标题〗Rational drug design and synthesis of a highly selective nonpeptide delt-opioid agonist,(4aS*,12aR*)-4a-(3-hydroxyphenyl)-2-methyl-1,2,3,4,4a,5,12,12a-octrahydropyrido[3,4-b]acridine (TAN-67)
〖合成方法〗The cyclization of perhydroisoquinoline (I) with o-amino-benzaldehyde (II) in the presence of methanesulfonic acid in refluxing EtOH gave the pyridoacridine (III).Subsequent cleavage of the methyl ether function using n-PrSH and tert-BuOK in boiling DMF provided the target phenol.

证明:(3-4cos2A+cos4A)/(3+4cos2A+cos4A)=tan四次方A 要详解
三角函数证明题(1)3+cos4a-4cos2a=8sin~4次方 a(2)tanatanb/tan2a-tana +
已知tan a=根号7 ,求cos4a-cos2a
请证明 sin4a-cos4a=sin2a-cos2a
化简[cos(4a-π/2)*sin(π/2-a)*cos2a]/[(1+cos2a)(1+cos4a)*cosa
tan(a+π/4)=3+2倍根号2,则1-cos2a/sin2a=
已知tan(a+π|4)=3+2根号2,求1-cos2a|sin2a
三角比:[cos(4a-PAI/2)*sin(PAI/2-2a)]/[(1+cos2a)*(1+cos4a)]
已知tan(4分之派+a)=2分之1,求1+cos2a分之sin2a-cos2a的值 要过程
已知a第三象限的角,cos2a= -3/5,则tan(π/4+2a)=?
已知a第三象限的角,cos2a= -3/5, 则tan(π/4+2a)=?
1.已知tan a=2/3,求sin2a-2sinacosa=4cos2a(2是平方)
