4-ISOPROPYL-1,4-CYCLOHEXADIEN-

Synthesis of (2S, 4S, 5S)-5-(t-Butoxycarbonylamino)-4-(t-Butyldimethylsilyloxy)-2-Isopropyl-7-Methyl Octanoic Acid

In an effort to produce renm mhibttory peptides, the preparation of (2 S ,4 S ,5 S )-5-( t -Butoxycarbonylamino)-4-( t -butyldimethylsilyloxy)-2-isopropyl-7-methyl octanotc acid, 15 , was carried out ( 1 ). This pseudo-dipeptide was used

Two‐Step, One‐Pot Synthesis of Inosine, Guanosine, and 2′‐Deoxyguanosine O6‐Ethers via Intermediate O6‐(Benzotriazol‐1‐yl) Derivatives

is evaporated and the O 6 ?(benzotriazol?1?yl) ether is treated with Cs2 CO3 and an appropriate alcohol, at room temperature. On the other hand, for reaction with phenols, Cs2 CO3 and the appropriate phenol are added to the reaction mixture without evaporation
