Problem with migrating multiple LEFT JOINS from Sybase to SQL Server

Hi

I'm migrating an SP from Sybase to SQL Server and in some query I have a multiple left outer join (*= operator)

table1.a *= table2.a
table1.c *= table3.c
table1.d *= table4.c
table2.e *= table5.e
table2.f *= table6.f
table5.g *= table7.g
table6.h *= table8.h

Which I'm trying to modify to SQL conventional LEFT JOIN, however I'm unable to make it work given that the same table is used in several places of the joins...

table1 left join with table2
table1 left join with table3
table1 left join with table4
table2 left join with table5
table2 left join with table6
table5 left join with table7
table6 left join with table8

Any ideas??
