Paragraph 0128; 0129; 0130, (2019/09/13)
The invention provides a borohydride reduction stabilizing system and a method for reducing ester into alcohol. The borohydride reduction stabilizing system comprises a borohydride reducing agent anda stabilizer for stabilizing the borohydride reducing agent, wherein the borohydride reducing agent is sodium borohydride or potassium borohydride, and the stabilizer is an alkali metal salt of alcohol. On the basis of an existing sodium borohydride/potassium reducing agent, an alcohol alkali metal salt (such as sodium alcoholate or potassium alcoholate) is added, and then the sodium borohydride/potassium reducing agent can keep stable and is not decomposed under a heating condition, so that on one hand, reduction activity is maintained in a relatively high state and the situation of excessiveuse is reduced, and on the other hand, generation of hydrogen is reduced and the process risk is reduced.

The pilot-plant synthesis of nevirapine analogue 1 is described. The compound was prepared in eight steps from substituted pyridine raw materials and 4-hydroxyquinoline. The key transformation involves a novel one-pot conversion of an arylhalide to arylac

Compounds represented by formula I: wherein R1 is H, halogen, (C1-4)alkyl, O(C1-4)alkyl, and haloalkyl; R2 is H or (C1-4)alkyl; R3 is H or (C1-4)alkyl; R4 is (C1-4)alkyl, (C1-4)alkyl(C3-7)cycloalkyl, or (C3-7)cycloalkyl; and Q is a fused phenyl-5 or 6-membered saturated heterocycle having one to two heteroatoms selected from O and N, said Q being optionally substituted with hydroxy, or (C1-4)alkyl which in turn maybe optionally substituted with pyridinyl-N-oxide or C(O)OR wherein R is H or (C1-4)alkyl; or a salt thereof. The compounds have inhibitory activity against Wild Type, and single and double mutants strains, of HIV.
