This work describes a convenient one-pot procedure for the synthesis of 2,2-disubstituted 2,3-dihydro-1H-naphtho[2,1-b]pyrans i.e. 2,2-disubstituted 1H-benzo[f]chromans} by the reaction of 2-tetralones and α,α-disubstituted β-hydroxy propionaldehydes under acidic conditions.
本工作描述了一种便捷的一锅法合成2,2-二取代的2,3-二氢-1H-萘并[2,1-b]吡喃(即2,2-二取代的1H-苯并[f]色满)的过程,该过程通过在酸性条件下,由2-四氢萘酮与α,α-二取代的β-羟基丙醛反应而实现。
