摘要

Two minor products each isolated in 3 yield bear on the sequence in the transformation of VI11-P X. One of these is assigned as compound IX3 by the correspondence of its melting point (95-96") and spectral properties with those previously reported. lo The other is assigned as a diastereomeric mixture corresponding to gross structure XIS3 Its broad melting range (76-96") and nmr (CDCI3) spectrum [T 8.67 and 8.72 (sum= 3 H), two ...
