A route to the 9,10-secosteroid astrogorgiadiol featuring a key sp 2-sp3 Suzuki type cross-coupling

The described semi-synthetic route differs from the previously published approaches by an original C-7-C-8 disconnection. The kinetic enol triflate of Grundmann ketone was chosen as the CD-ring platform on which to couple an A-ring synthon via a challengi

Synthesis of (-)-astrogorgiadiol

Reaction of Rh2(S)-PTPA4 with the (R)-citronellol-derived α-diazo-β-ketoester 1 led to the formation of cyclic β-ketoester 2 in 95% yield and 48% diastereomeric excess. The purity of 2 was increased to >99% de after one crystallization. To demonstrate its utility in steroid total synthesis, the β-ketoester 2 was carried on to secosteroid (-)-astrogorgiadiol (3), a naturally occuring vitamin D analogue with antiproliferative properties.
