Abstract
The interaction of octahydroxytetraheptyl[l 4 ]methacyclophane 1 with bis( N,N -diethylamido)menthylphosphite under mild conditions with a different ratio of initial reagents (1 : 8, 1 : 4, 1 : 2) yields either the completely phosphorylated optically active product (for ratio 1:8), or the product of partial phosphorylation (for ratio 1:4); the corresponding phosphates and thiophosphates also were obtained. An optically inactive product with two tetraresorcinol fragments united by phosphite bridges is formed under more severe reaction conditions and with a ratio of reagents 1 : 2.
