Short Enantioselective Syntheses of trans-5-Alkylprolines from New Functionalized Amino Alcohols
摘要:
GraphicsAmino alcohols, having an enol ether function, cyclized in acidic medium to give quantitatively diastereosomerically pure bicyclic compounds that were transformed in five steps in enantiopure trans-5-alkylproline derivatives.
Diastereoselective additions of methoxypropene-derived lithium and zinc reagents to oxazolidines are investigated. The lithium allylic carbanion reacts with oxazolidines to afford mainly the β-amino alcohols with an enolether function (y-adduct) and the zinc derivative leads to amino alcohols with an allyl ether function (a-adduct).
Provided are a histone acetylase p300 inhibitor and a use thereof, belonging to the filed of medicinal chemistry technology. A compound represented by formula (I), or a stereochemical isomer thereof, or a solvate thereof, or a pharmaceutically acceptable salt thereof, can inhibit the activity of histone acetylase p300 and inhibit the proliferation activity of a variety of tumor cells.
