Studies directed to the total synthesis of ET 743 and analogues thereof: An expeditious route to the ABFGH subunit

(matrix presented) In model studies directed to the total synthesis of Et743, a strategic S-C bond formation in systems 26 and 27 was demonstrated. It was further shown that Pictet-Spengler cyclization leading to spiro product 33 exhibits very high stereo
