Vinylphosphonium salt mediated reaction between alkyl propiolates and aminophenols or hydroxyphenols

Addition of catechol to methyl propiolate or ethyl phenylpropiolate in the presence of Ph3P leads to methyl 2-(1,3-benzodioxol-2-yl)acetate or 3-(1-phenylmethylidene)-1,4-benzodioxin-2-one. 2-Aminophenols react with alkyl propiolates in the pre

Rhodium Carbenoid O-H Insertion Reactions With Phenols; A Facile Method for the Synthesis of Trialkyl 2-Aryloxyphosphonoacetates and Their Use in the Preparation of 2-Aryloxy-3-phenylpropanoates.

A variety of substituted phenols undergo a facile and hitherto unreported rhodium carbenoid mediated O-H insertion reaction with trialkyl 2-diazophosphonoacetates 7 to afford the corresponding trialkyl 2-aryloxyphosphonoacetates 5 in generally good to exc

RING OPENING AND RING-CHAIN TAUTERISM IN 2-CARBALKOXY- AND 2-ACYL-2,3-DIHYDRO-1,4-BENZODIOXINS.

The behaviour of benzodioxin esters 1a-c and ketones 2a-c under the action of K2CO3 in acetone and of NaH in DMSO has been studied; the experiments were also carried out in the presence of scavengers of phenolic intermediates or products.Under the action
